APPENDAGE: Rev (9/1/2012) LIFT ENVIRONMENT LIMITATIONS: Mohawk prohibits the outdoor installation of this standard lift, which is APPROVED FOR INDOOR USAGE ONLY, in a normal garage type environment. Any concerns in applications that expose the lift to additional environmental effects, such as paint booths, wash bays, outdoors, high or low temperatures, etc. must be addressed to our engineering department, where provisions could/may be made to the lift to accommodate the area of use.
POWER SUPPLY REQUIREMENTS This lift comes with (2) 12 VDC batteries in series to provide a 24 VDC system. A separate 120 VAC power supply is only required when charging the post. Each post comes equipped with a 120 VAC, 60 HZ receptacle which accepts a 120 VAC extension cord. The minimum amp draw is 3 amps per post. Use sizes of plug, cord and power supply as follows: Plug Requirements: NEMA Type 5-15 (Female), 125 VAC, 2 Pole, 3 Wire Grounding, 15 Amp Rated.
OPTIONAL EQUIPMENT Note: Refer to Option Equipment Section in the back of this manual for specific user instructions for option available for this lift. The standard mobile lift is suitable to lift wheeled vehicles by the tires. It normally comes in pairs of columns totaling 2, 4, 6 or 8 column systems. Ordering additional dummy plugs may enable one lift to be used in a variety of combinations simultaneously. A hand control pendant is available and can be connected to any column.
DESIGN AND CONSTRUCTION The standard mobile lift is suitable to lift wheeled vehicles by the tires. It normally comes in pairs of columns totaling 2, 4, 6 or 8 column systems. Each column consists of a rigid frame of three-wheel design for maneuverability, lifting carriages with tire forks, control panel, electric-hydraulic power unit, and hydraulic cylinder. Two of the wheels are spring loaded and in fixed positions on the column base.
MOBILE LIFT SET-UP THOROUGHLY READ THIS SECTION BEFORE OPERATING THE LIFT. IF YOU HAVE ANY QUESTIONS, GET THEM ANSWERED BEFORE PROCEEDING. REFER TO ANSI/ALI ALIS “SAFETY REQUIREMENTS FOR INSTALLATION AND SERVICE OF AUTOMOTIVE LIFTS.” 1. Be sure that the floor is strong enough to support the lift before operating. Do not use the lift on asphalt surfaces, as the lift will sink (cause depressions in the asphalt) if the vehicle is on the lift for any extended period of time.
7. Press the release lever to lower all jacking wheels on back of all posts after positioning. 8. Connect the communication cables from post to post in a daisy-chain fashion. For example: Posts 1 to 3 to 4 to 2 for a 4-post setup. Place dummy plugs (male and female ends) at the posts at the end of the chain. (See figure below) Note: This lift indicates what posts are communicating within the system at start up.
MOBILE LIFT OPERATION 1. Perform Lift Setup as stated in previous section. 2. Disengage all E-STOP buttons at each post by turning them clockwise to release them. Turn on the main switch for each post to “OPERATE LIFT”. The display will light up to indicate the post power is on. Repeat for each post in the system. Notice that the displays will indicate which posts are communicating in the system. Verify this configuration to continue operation. The system is now ready to operate. 3.
7. PAIR OPERATION To raise, lower or park only a pair of wheels, turn the selector switch to PAIR at the post pair that control is desired, while pressing the RAISE, LOWER or PARK button. NOTE: Be sure that the set of wheels on the ground is free to move as the effective distance between the front and rear wheels becomes less as one pair of wheels is higher or lower than the other pair. Keep the height difference between pairs as low as practical.
LIFT FINAL CHECKOUT (AFTER INSTALLATION): REV (9/1/2012) THIS PROCEDURE OUTLINES THE FINAL CHECKS TO MAKE AFTER INITIAL INSTALLATION OF THE LIFT UNIT. REPEAT THIS PROCEDURE IF THE LIFT IS RELOCATED.
AUTOMOTIVE LIFT SAFETY TIPS Post these safety tips where they will be constant reminder to your lift operator. For information specification to the lift, always refer to the lift manufacturer’s manual 1. Inspects your lift daily. Never operates if it malfunctions or if it has broken or damaged parts. Repairs should be made with original equipment parts. 2. Operating controls are designed to disengage when released. Do not block closed or override them. 3. Never overload your lift.
MAINTENANCE INSTRUCTIONS 1. The channel sections where the carriage bearings ride against should be cleaned and lubricated twice a year (once every 6 months) using a light lubricant (WD-40). The channel sections where the slide blocks ride against should be cleaned and lubricated twice a year (once every 6 months) using a light lubricant (WD-40). 2. The main carriage bearings are factory lubricated and do not require any additional periodic lubrication.
EXPLANATION OF COMPUTER SYSTEM SYSTEM ACTIVATION All posts on this system are identical (there is no master or slave columns). After the posts are connected as described in the lift setup, the lift is ready to be activated. As each post is turned on, they “search” for each other, establishing a shared network for synchronizing and controlling the lift as a system. The first thing the user must do to operate the lift is to verify that the network is detecting the desired number of columns to use.
FUNCTION OF STRING POTENTIOMETER (String-Pot) There is a string potentiometer (string-pot) mounted on the top of each column, and connected to each carriage, which senses the movement of the carriage. The string-pot sends an absolute analog (4-20mA) signal to the PLC as the string is pulled in and out of the sensor. This signal is absolute, which means that the lift will always know the height of the lift, even when powered off and on again.
F3: Weight Display This screen will display 1 of 3 screens, depending if the lift has the hydraulic pressure sensing option present. If all the posts in the system have the pressure sense option, the screen (A) will display showing the weight on the post and the total weight of the system. If only the present column has the pressure sense option, then screen (B) will display, showing only the post weight. If you are at a column that does not have a pressure sense option, then screen (C) will display.
F5: User Settings Display This screen displays general user settings of the lift. Pressing enter and the up or down arrow keys will scroll through this menu. Press Escape and the Exit Key to Exit Menu.
F9: Factory Settings (Factory Password Protected) This screen displays factory settings. This is only accessible with the factory password (See F10). F10: Password This screen allows entry of the password which will give access to the PLC configuration settings and screens F9 and F10. Enter either the Distributor Password to give limited access to F7 screen, or the Factory Password to give access to all password protected screens.
Comms Lost Error: This screen appears if any column in the system is lost after it was previously present. This could be due to a column being turned off or if the communications to the post are not connected. The post in which communications is lost will be identified on the screen. All controls will be locked-out until this is remedied. i.e. The display to the left shows loss of communications to post 3.
Maximum Offset Error: There are limits on how far any post can be out of level from any other post, even when using Single and Pair overrides. If any post reaches its limits, one of the following screens will be displayed (depending on if the unit is being used in All, Pair, or Single). The highest and lowest posts will be identified. Raising is only allowed on the lowest post, Lowering only allowed on the Highest post.
Post Overload Error: (Optional) This screen will appear if any post has a weight on it that exceeds the capacity of the post. Post capacities are set in the factory setting menu. Raising and parking are not allowed in this situation, only lowering. (This error will only be present if the lift has the pressure sensing option.) i.e. The display to the left shows that post 3 & 4 are overloaded. Battery Warning: This indicates that one of the post’s batteries are low on charge and need to be recharged.
TROUBLE SHOOTING NOTICE: Read manual prior to trouble shooting. A good understanding of how this lift and its controls function will greatly help in understanding any problems that may occur. START-UP: Problem: Upon power up, screen does not illuminate (on any single column). Solution1: Verify that power cables are unplugged from charger inlets on all posts. Post will not power up unless power is removed from charger. Solution2: Check to see that battery cables are connected to batteries properly.
Solution2: Jack is low on oil. Add oil. (Dexron III AFT or equivalent) Problem: Carriage is lowering on its own. Solution1: Check that there are no oil leaks by checking around the column. If so, repair the leak condition. Solution2: If Solution 1 does no produce results, check for leakage of cylinder piston seals. Remove black plastic vent tube from power unit reservoir tank port and see if any fluid is flowing out. If so, cylinder piston seals are leaking. Contact Mohawk’s Service department.

Charger Status Lights: Each post comes equipped with a dual battery charger which provides charging for two 12 VDC batteries (in series makes 24 VDC). Each charger is rated for 120 VAC, 60 Hz, 4 Amp draw. Keep this in mind if using extension cords and multiple adapters into a single outlet. (4 chargers will draw 4 x 4 amps = 16 amps total). There are three charging levels that the charger progresses through to full charge. Refer to the MINN KOTA MK220D manual enclosed at end of this manual.
Battery Status Indicator: The front panel of each post has a battery level indicator which shows the current charge of the batteries. (Battery level is also available by pressing the F3 button.) Be aware that the lower the battery level is, the higher the amp draw, and thus the deeper the level of charge drawn by the batteries. Paying attention to these meters and using a regular recharge routine will provide the user with years of trouble free usage.
Jack Operation: Prior to moving posts, the rear jack wheels must be engaged. To do this, push black lever down, then jack handle to desired height. When post is in position, collapse jack wheel fully by pulling black lever up.

TECHNICAL MANUAL Valve-Regulated Lead-Acid (VRLA): Gelled Electrolyte (gel) and Absorbed Glass Mat (AGM) Batteries EAST PENN Expertise and American Workmanship Quality System Certified to ISO 9001 Introduction • is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended. Valve-regulated lead-acid (VRLA) technology encompasses both gelled electrolyte and absorbed glass mat (AGM) batteries.
What is the difference between VRLA batteries and traditional wet batteries? Can our VRLA batteries be used as starting batteries as well? Wet batteries do not have special pressurized sealing vents, as they do not work on the recombination principle. They contain liquid electrolyte that can spill and cause corrosion if tipped or punctured. Therefore, they are not air transportable without special containers. They cannot be shipped via UPS or Parcel Post or used near sensitive electronic equipment.

Answers to the Most Frequently Asked Questions NOTE: Before reviewing this section, be sure you understand the difference between gel, AGM, and flooded batteries.
Why can’t VRLA batteries be opened? • Our VRLA batteries are protected against deep discharge because they are “acid-starved.” This means that the battery uses the power in the acid before it uses the power in the plates. Therefore, the plates are never subjected to destructive ultra-deep discharges. VRLA (Valve-Regulated Lead-Acid) batteries, sometimes called SLA (Sealed Lead-Acid) batteries or SVR (Sealed Valve-Regulated) batteries work on a recombination principle.
Follow these tips for the longest life: • Avoid ultra-deep discharges. • Don’t leave a battery at a low stage of charge for an extended length of time. Charge a discharged battery as soon as possible. • Don’t cycle a battery at a low state of charge without regularly recharging fully. • Use the highest initial charging current available (up to 30% of the 20-hour capacity per hour) while staying within the proper temperature-compensated voltage range.

How can continual undercharging harm a battery? What is a thermal runaway? The appropriate charge voltage depends on the battery temperature (see page 11). A warmer battery requires a reduced voltage. If the voltage is not reduced, current accepted by the battery increases. When the current increases, the heating increases. This can continue in a loop feeding on itself with the battery temperature and charging current rising to destructive levels.
e. At the end of charge (when the current is very low or goes to zero) check and record the voltage. Note that the charger may have turned off by then. f. The disconnected battery should be at 100% or above after a 24 hour rest. During the charging time, the charger should not have exceeded the limit (except for occasional, brief pulses). This indicates that the charger is working properly. The valves only let gas out, never in. A partial vacuum can form within a sealed battery under various circumstances.
Also, when protected against short circuits and securely braced/ blocked, our VRLA batteries “are not subject to any other requirements of 49 CFR Parts 171-180…” for shipping. g. Spray exposed terminals and connectors with several coats of battery terminal corrosion protection spray. (Mask surrounding areas to protect against overspray.) h. For batteries which may be exposed to very wet environments (e.g. bilge mounted batteries) total encasement of the exposed terminals and connectors is necessary.
To properly recharge, a sophisticated “battery isolator” should be installed. Otherwise, one battery will be continually overcharged and the other undercharged in a dual-voltage set-up. IMPORTANT: Do not install any type of battery in a completely sealed box or enclosure. In the event of overcharging, the potentially explosive gasses must be allowed to escape. During recharge, the current (amps) is split between the batteries.
AD N UR • SPARKS • FLAMES • SMOKING CAN CAUSE BLINDNESS OR SEVERE BURNS. SULFURIC ACID GET MEDICAL HELP FAST. 1. Perform a visual inspection. Inspect for defective or cracked case and cover, and loose or damaged terminal posts or cables. Replace battery and/ or cables immediately if any damage is found. Always wear safety glasses when working around batteries. Batteries can explode! Protect your eyes. SERVICE TIPS ..
