OPERATION BEFORE USE 1. Add Engine Oil (New machines will be pre-oiled from MAKINEX) 1.1 Place Pressure Washer on a flat, level surface. 1.2 Clean area around oil fill and remove oil fill cap. 1.3 Using oil funnel (optional), slowly pour contents into oil fill opening. (Oil capacity is 1.1L) 1.4 Replace oil fill cap and tighten. NOTE: IMPROPER treatment of pressure washer can damage it and shorten its life.
WHEN ADDING FUEL TO PRESSURE WASHER, OBSERVE THE FOLLOWING STEPS: 2.1 Turn pressure washer OFF and let it cool for at least two minutes before removing fuel cap. Loosen fuel cap slowly to release pressure. 2.2 Fill fuel tank outdoors. 2.3 DO NOT overfill fuel tank. Leave room for fuel to expand. 2.4 Wait for spilled fuel to evaporate before cranking engine. 2.5 Keep fuel away from sparks, open flames, pilot lights, heat and other ignition sources. 2.
OPERATING YOUR PRESSURE WASHER 1. How to Pre-start your pressure washer To start your pressure washer for the first time, follow these instructions. This information also applies if you let the pressure washer sit idle for at least a day. 1.1 Place pressure washer near an outside water source capable of supplying water at a flow rate at least 5 gallons/19L per minute and no less than 20 psi at pressure washer end of garden hose. 1.
3. Connect garden hose to water inlet connector 3.1 Before connecting the garden hose to the water inlet connector, inspect the filter 3.2 Run water through your garden hose for 30 seconds to clean put any debris 3.3 Release any pressure from spray gun by pulling the trigger. 3.4 Connect the garden hose to the water inlet connector (not to exceed 15m/50ft in length and with the inner diameter of hose no less than 13mm). 3.
4. Adjust valve position to Roto-Clean CORRECT POSITION 4.1 Make sure the valve is pointing to the Roto-Clean position before starting as this makes sure pressure is constantly released before you start the engine and during initial running. WARNING RISK OF EYE INJURY. SPRAY CAN SPLASH BACK OR PROPEL OBJECTS Always wear safety goggles when using this equipment or in vicinity of where equipment is in use. Before starting the pressure washer, be sure you are wearing adequate safety goggles.
***IMPORTANT*** DO NOT run the pump without the water supply connected and turned on. Damage to equipment resulting from failure to follow this instruction will VOID WARRANTY 6. Checking/adjusting pressure The MAKINEX dual pressure washer operating pressure is pre-adjusted to 2500 Psi. Over adjusting pressure will VOID WARRANTY. 6.1 Check the operating pressure when the machine starts; allow some time to build up pressure. 6.2 The by-pass valve has a knob to adjust pressure.
7. Two types of operations By using the valve, you can choose between two types of operation.
8. Nozzle selection The nozzle on the spray gun that comes with the MAKINEX dual pressure washer is a ¼ NPT M 15° Size 3. Your Roto-clean will come installed with one set of 25015 nozzles (25 degree 1.5 orifice). The minimum orifice to be used in your Roto-clean is half that which is being used in your pressure washer. Example: If your pressure washer uses a size 5 orifice, you need to use a size 2.5 orifice in your Roto-clean.
9. Foldable Handle 8.1 release the lock pin by pressing down on spring tab of the handle lock tab. Refer to above. 8.2 Use both hands at the same time. 8.3 Lock pin will spring into place at their designated grooves.
10. How to stop your pressure washer 10.1 Turn off the engine 10.2 Release pressure from spray gun, ALWAYS point gun in safe position before pressing trigger. NOTE: Spray gun traps high water pressure, even when engine is stopped and water is disconnected. 10.3 Move throttle control lever on engine to stop position 10.
MAINTENANCE General Recommendations: Regular maintenance will improve the performance and extend the life of the pressure washer. The pressure washer’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the pressure washer as instructed in this manual and in the engine manual, including proper storage as detailed in Winter Storage and Long Term Storage.
Pressure Washer Maintenance Clean Debris Daily or before use, clean accumulated debris from cleaning system. Keep the unit clean at all times. Keep area around and behind muffler free from any combustible debris. Inspect cooling air slots and openings on the pressure washer. These openings must be kept clean and unobstructed. NOTE: IMPROPER treatment of pressure washer can damage it and shorten its life. DO NOT spray any objects through cooling slots.
Check Spray Gun Examine the hose connection to the spray gun and make sure it is secure, and make sure the ‘safety lock’ is present and attach on the trigger, it helps to prevent any accidental jets when in operation. Replace spray gun immediately if the safety lock is damaged or not functioning. Check Wand Occasionally, the spray wand can be clogged with foreign materials such as dirt. When this happens, excessive pressure can develop.
12. Use same nozzle maintenance with the Roto-clean. If pressure drops off check nozzle for wear. Nozzles should be replaced on a regular basis (suggestion: every month for machines in regular use, every three months for machines used intermittently). Using the machine with the incorrect nozzle size or worn nozzle will VOID WARRANTY and can be DANGEROUS to operator.
Checking the oil level Check the oil with the pump level and cold. Check the amount of oil through the level gauge (A). If necessary, top up with oil with the characteristics specified in the ‘lubricants table’. To top up with oil proceed as described below. 1. Unscrew the plug (B) and pour oil in until it is halfway up the level gauge (A). 2. Screw on the plug (B). Position the machine in which the pump is incorporated perfectly level, with the pump slightly warm.
Lengthy pump lay-offs If the pump is to be unused for a long time, proceed as described below. 1. Run the pump with clean water for a few minutes. 2. Operate the pump without water for 10 seconds with the end of the delivery pipeline open to empty the pump and the delivery circuit and prevent scaling. 3. Flush the pump with water and solvents authorised by the relevant laws. 4. Dry the pump with a pressurised air jet. 5. Protect the pump from weather.
Roto-clean Maintenance The Roto-clean must be maintained to ensure correct function and longevity of life. There are two nozzles attached and they need to be checked before every use and are similar to nozzle maintenance of the spray gun. We recommend that you supply grease to the rotary head every 30 – 40 hours of use (if frequent usage, grease every 20-30 hours of operation). Simply add a small squirt of automotive grease, do not overfill with grease as it will bog down the rotary head.
STORAGE Long term storage instructions (fuel in tank) Gasoline fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or crucial carburetor parts. To keep fuel fresh, add a fuel stabiliser liquid additive to fuel. The fuel stabiliser is available at most auto parts stores. Draining gasoline is unnecessary if the fuel stabiliser is used according to the instructions that come with it.
Storage of Pressure washer 1. Drain all water from high pressure line, coil it and store it in cradle of pressure washer handle. 2. Drain all water from spray gun and spray wand by holding spray gun in vertical position with nozzle pointed downward. Squeeze trigger to remove fluids from spray gun and spray wand. Store in spray gun holder. 3. Store high pressure hose and spray wand so they are protected from damage.
Charge the battery For pressure washer equipped with batteries for electric starting, proper battery maintenance and storage should be followed. An automatic battery charger with automatic trickle charging capability should be used to charge the battery. Maximum charging rate should not exceed 1.5amps. Follow the instructions included with the battery charger. The battery should be fully charged at least once per month. Other Storage tips 1.
