SAFETY PRECAUTIONS SAFETY FIRST This symbol, the industry’s «Safety Alert Symbol», is used throughout this manual and on labels on the machine itself to warn of the possibility of personal injury. Read these instructions carefully. It is essential that you read the instructions and safety regulations before you attempt to assemble or use this machine.
SAFETY PRECAUTIONS 11. Never operate the pump without water supply. 12. Never let the burner run when the oil tank is empty. 13. Children and pets must be kept away from the area of operation due to a possibility of burns from hot machine components or injury from any equipment. 14. Refuel in a well-ventilated area with the equipment stopped. If any fuel is spilled, clean it up completely and allow vapors to dissipate before starting the machine again.
INSTALLATION INSTRUCTIONS 1. Install the hydraulic straight fitting (A on figure 1) to the reel exit. 2. Install the hydraulic elbow fitting (B on figure 2) to the reel entry. 3. Install the reel to the reel support with 5/16" NC x 3/4" bolts, 5/16" lockwashers and 5/16" flat washers (C, D and E on figure 3). 4. Connect the hose coming from the coil to the hydraulic elbow fitting at the reel entry. 5. Install the storage compartment (F on figure 5) with 5/16" NC x 1" bolts, 5/16" lockwashers and 5/16" flat washers (G, H and I on figure 5). 6. Connect the electric connector located at the end of the burner switch harness. 7. Install the handlle (J on figure 7) with 5/16" NC x 2 1/4" bolts, 5/16" washers and 5/16" nylon locknuts (K, L and M on figure 7). 8. Connect the spray gun hose to the hydraulic straight fitting located at the reel exit. Roll the hose on the reel.
OPERATION INSTRUCTIONS Preparation 1. Make sure that all hoses are in good state, not cracked or crushed. 2. Check the oil level of the pump. Pump must be in a level position. Oil level must be halfway on the sight glass (A on figure 1) or visible on the dipstick (B on figure 1). 3. Check the oil level of the engine. Engine must be in a level position. Remove the oil filler cap/ dipstick (C on figure 1). Oil level should be at bottom edge of the oil fill hole.
OPERATION INSTRUCTIONS Starting the engine DO NOT START THE ENGINE WITHOUT SUPPLYING WATER TO THE PUMP These instructions will be useful for the following sections and will be referred to as “start the engine”. Starting the engine with the electric starter: 1. Turn down the fuel valve (J on figure 6) to open.
OPERATION INSTRUCTIONS Cold water pressure washing 1. Fill the fuel tanks (see “Filling the fuel tanks” previous section). 2. Remove the washing nozzle or weed killing tool at the wand outlet (O on figure 7). 3. Connect a water supply hose at the machine inlet (P on figure 7) and open the hose valve. The supply hose flow rate must be at least 4 gpm (15 l/min). 4. Turn the mode selection valve (Q on figure 7) on the side of the machine, to “Washer” position. 5. Depress the gun trigger (R on figure 8) until water flows out limpid and regularly. Release the gun trigger. Figure 7 6. Install a high pressure nozzle (S on figure 8) at the wand outlet (T on figure 9): Yellow = 15° angle, heavy dirt Green = 25° angle, medium dirt White = 40° angle, light dirt or rinse.
OPERATION INSTRUCTIONS Injecting soap 1. If the machine is running in hot water pressure washing mode, turn off the burner switch (W on figure 11) and keep water flowing until its temperature is less than 100°F (40°C). 2. Remove the high pressure nozzle at the wand outlet and replace it by the black soap nozzle (X on figure 12). 3. Insert the soap filter and hose (Y on figure 13) in a liquid soap container. 4. Rate of injected soap can be adjusted using the soap valve (Z on figure 13). 5. Depress the gun trigger. Water and soap mix will take 30 seconds to reach the nozzle and flow out. 6. Once soap application is finished, remove the soap nozzle and install a high pressure nozzle to rinse (yellow, green or white). Soap will flow out for 30 seconds and then stop. IMPORTANT: • If corrosive products have been injected, rinse injector by injecting water for a couple of minutes. Weed killing 1. Fill the fuel tanks (see “Filling the fuel tanks” previous section). 2. Remove the washing nozzle or weed killing tool at the wand outlet (AA on figure 14). 3. Connect a water supply hose at the machine inlet (BB on figure 14) and open the hose valve. The supply hose flow rate must be at least 4 gpm (15 l/min). 4. Turn the mode selection valve (CC on figure 14) on the side of the machine, to “Weed killer” position. 5. Depress the gun trigger (DD on figure 15) until water flows out limpid and regularly. Release the gun trigger. 6. Install the weed killing tool (EE on figure 16) at the wand outlet (FF on figure 16). 7. Start the engine according to “Starting the engine” previous section and set the speed to full throttle. 8. Turn on the burner switch (GG on figure 17).
OPERATION INSTRUCTIONS Stopping procedure 1. If the machine has been used for hot water pressure washing or for weed killing, turn off the burner switch (LL on figure 21). 2. If the machine has been used for soap injecting, install a high pressure yellow, green or white nozzle (MM on figure 22) at wand outlet (NN on figure 22). 3. Depress the gun trigger until water flows out limpid and regularly, and at a temperature of less than 100°F (40°C).
MAINTENANCE Engine oil change The first engine oil change must be done after 10 hours of use. The next oil changes must be done after every 50 hours of use. 1. Place a container under the machine to recover used oil. 2. Unscrew the oil drain plug (A on figure 1).
MAINTENANCE Battery DISCONNECTED BATTERY: When you receive your high pressure washer/weed killer, the battery has been disconnected to avoid long term discharging. INITIAL START-UP: Recharge the battery to full capacity before connecting it to the machine. Look for the positive wire (G on figure 5) between the engine and the heating coil. Take off the plastic insulator and keep it in the storage compartment for further use. Make sure that the now non-protected connector does not touch grounded metallic parts.
MAINTENANCE WARNING: • The battery contains sulphuric acid. Avoid contact with skin, eyes or cloths. Wear rubber gloves and eyeglasses or visor when handling, filling or recharging the battery. If electrolyte splashes in the eyes or on the skin, rinse with a large quantity of pure water and call a physician immediately. • The battery produces gaseous hydrogen and oxygen while recharging. Keep away all sources of lighting. When checking electrolyte level, use a flashlight or permanent light for lighting. Do not turn on or turn off the lighting source near the battery. Do not smoke or produce sparks. CAUTION: • Always disconnect the battery before recharging.
MAINTENANCE Storage If the machine is to be stored for a long time, take the following precautions: 1. Winterize the machine. Follow instructions specified at the end of previous section. 2. Using a siphon, empty the engine gas tank. 3. Recirculate antifreeze. Suck antifreeze from the container and return it into the same container. To empty the carburetor, start the engine and let it run until engine stops by itself.
