all openings and moving parts.
15. Use extra care when using on stairs.
16. To reduce the risk of re or electric shock, do not use this machine with
a solid-state speed control device.
17. The voltage and frequency indicated on the name plate must corre-
spond to the wall receptacle supply voltage.
18. When cleaning and servicing the machine, local or national regulations
may apply to the safe disposal of liquids which may contain: chemicals,
grease, oil, acid, alkalines, or other dangerous liquids.
19. Do not leave operating unattended.
Preparation
1. Remove furniture and other items from the area you are going to clean.
2. Vacuum carpet and upholstery, and remove debris.
3. Protect cabinets, walls and painted surfaces with drop cloths or plastic.
4. Inspect power cords for damages.
Operating Instructions
1. Fill the solution tank.
2. Attach female end of a solution hose to a wand or other tool and the
male end to the LTD’s Quick Disconnect (QD).
3. Attach one end of a vacuum hose to a wand or other tool and the other
end to the LTD’s 2” Cuff-Lynx vacuum hose ports.
4. Plug in power cords:
LTD3/5/12 Model: Using two separate circuits/breakers, plug in the
grounded power cables as previously instructed using the appropriate
grounding techniques.
The amber indicator to the left of the PSI gauge will illuminate and sound
a tone when plugged into separate circuits/breakers.
1. Activate the switches using the following steps:
2. When the hoses are attached, turn Pump-Out Switche.
3. The Prime Valve and Pressure Regulator are located on the front right
side of the solution tank and should be primed prior to use. To prime the
pump turn the valve to the Prime position for 30 seconds, and then turn
horizontally to the Run position.
4. Pull your wand’s trigger to ensure water is running through the lines to
avoid damage to the Pump and Heating unit (LTD3).
5. (LTD3) The heater switch has three positions: Off (Middle); 1,000 watts
using 1 heater (Top); 600 watts & 1,600 watts using 2 heaters (Bottom)
If the water heater is to be used, prime system and turn it on to the desired
wattage and wait ve minutes for the water to reach temperature.
6. To clean, make two dry passes for every one wet pass while work-
ing away from the power cords. For optimal use or heavily soiled areas,
repeat wash steps in the opposite direction.
7. To prevent motor or internal damage, use a preferred foam control
solution in the recovery tank. Remember to check for build-up in both the
recovery and solution tanks!
8. Empty the Recovery Tank when the internal shut off disengages the
vacuum. Attach the 45º drain elbow to the drain spout located in the back
and lift the dump valve to empty the tank.
9. Squeeze the wand or tool’s trigger for ve seconds after turning the
power switches off to relieve any existing line pressure.
10. When the machine is off: unplug the power cables, remove solution
and vacuum hoses, and empty the recovery tank by attaching the 45º
drain elbow.
11. To empty the solution tank, twist off the solution tank drain cap located
on the back of the machine.
After Use
1. Before storing the machine, drain, rinse and dry both the tanks and
vacuum hoses of any residual water or solution.
2. Store standing upright in a dry, enclosed location.
3. Leave the recovery tank lid open for better air circulation.
4. If storing in freezing temperatures, take extra precautions to make sure
the machine and solution systems are completely drained and dry.

Oil Maintenance
Each machine using the General Pump Head(add TM or C icon) will need
its rst its rst oil change within 50-100 hours of use, then every three
months for 500 hours after that. Regular lubrication is the easiest, most
efcient and least expensive element in preventative maintenance
according to the manufacturer, General Pump.
Required Equipment:
1. 9/16” Wrench or socket.
2. 7/8” Socket with ratchet to t.
3. 11 oz SAE 30w Oil
4. Oil catch pan capable of holding 11 oz of oil (Height ≤ 2”)
5. Oil funnel capable of tting oil port on top of General Pump head brass
tee (3/8” diameter)
6. Flash light (Optional)
Instructions:
1. Cover ground with cardboard or any available scrap material to prevent
unwanted spills and stains.
2. Slide ≤ 2” oil catch pan under the ball valve located under the bottom
front of the machine and to the left of the solution tank drain.
3. Release the two rear latches by turning its wings to the left then open
top half of the machine completely to expose the main pump.
4. Remove the 9/16” oil cap from the brass tee on top of the General
Pump head.
5. Unscrew then 7/8” oil plug from under the machine until nger loose.
6. Once the oil has stopped or slowed to a few drips, replace the lower oil
plug then tighten it with a 7/8” socket.
7. Using a funnel, pour 11oz of SAE 30w oil into the top of the General
Pump head through the brass tee.
8. Use a ashlight to check the side of the General Head to ensure the oil
level reaches the midpoint of the view glass. Add or remove oil as needed.
9. Replace the 9/16” plug on top of the brass tee using a wrench or socket.
10. Close the machine and re-latch its rear to avoid any separation during
transport.
11. Dispose of any old oil and continue normal use of the machine.
Filter Maintenance
All LTD models have six lters that need to be checked and cleaned after
each week of use. Regular lter maintenance is a simple way to extend
the life of your machines.
Vacuum Stack Filters:
Located inside of the black vacuum tank are two pvc vacuum stacks. Each
stack has one foam lter to help prevent waste material from getting into
