Be sure latch is pushed fully down or it will not prevent the gun from being triggered. • When using a sandblasting kit, refer the sandblaster kit instruction manual for detailed operating and cleaning information. 1. Check oil level of engine and pump. 2. Check fuel level. 3. Check oil level in pump. It should be half way up the sight glass, located on the front of the pump. Add pump oil as necessary. The system is equipped with a thermal overload to help prevent severe damage. 4. Turn on water supply. . 5. Trigger gun until a constant stream of water sprays from the tip, indicating air is purged from the system. 6. Open fuel shutoff valve. Be sure spark plug ignition cable is pushed firmly on the spark plug. • All Honda engine-powered pressure washers are equipped with an engine low-oil sensor that shuts the engine off when the oil level falls below a certain level. • If the engine stops unexpectedly, check the oil and fuel levels. • Check the oil level each time you add fuel. ti5437a engaged disengaged ti5428a ti5429a Fuel level After the first 50 hours of operation, drain and refill pump oil. CAUTION Always be sure the water supply is completely turned on before you run the pressure washer. Never run pressure washer without water. Costly pump damage will result. ti5430a Oil level ti5431a ti5433a ON Operation 7. Move switch to ON position and set throttle to HALF throttle position. ONOFF ti5434a CAUTION • Do not allow pressure washer to idle for more than 10 minutes. This causes the recirculating water to overheat and can seriously damage the pump. • Turn off pressure washer if it will not be spraying at least every 10 minutes. If heated inlet water is used, reduce this time more. • Do not operate pressure washer with inlet water screen removed. This screen help keep abrasive sediment out of pump. This sediment could clog pump or damage cylinders. Keep screen clean. • Do not pump caustic materials which could corrode pump components. 8. Trigger gun to produce a constant stream of water and, at the same time, pull starter rope quickly to start the engine. Pull and return rope until the engine starts. HINT: Placing one foot on the pressure washer as a brace provides better leverage. • For easier starting, have one person start pressure washer while another triggers gun. • If engine is cold, before starting engine, close choke completely. In cool weather you might have to run engine for the first 10-30 seconds with the choke closed. In warm weather, open choke completely as soon as engine starts. • If engine is warm, start engine with choke completely open or only partially closed. When engine starts, open choke completely. OPEN HALF CLOSED ti5436a Chemical Injector Operation 1. Follow Pressure Relief Procedure (page 6). 2. Insert chemical filter (attached with clear tubing to chemical injector) into the chemical container. Insert brass coupler into chemical injector. ti5435a ti5438a 309286K 3. Install black (large orifice) chemical tip (Installing and Changing Spray Tips, page 9). The large orifice of the chemical tip causes a drop in pressure that actuates the chemical injector. Changing back to a small orifice spray tip, deactivates the chemical injector and produces high pressure for rinsing. The chemical filter can be left in the chemical container during high pressure spraying. To regulate the flow rate of the chemical, turn the chemical adjustment knob on the injector. ti5439a Operation Installing and Changing Spray Tips Spray tips have 4-or 5-digit numbers on them. The first two digits are the spray angle. Spray Tip No. Spray Pattern Fan Angle 00XXX 0° blaster (red) 15XXX 15° (yellow) 25XXX 25° (green) 40XXX 40° (white) Chemical* XX° (black) *The chemical injector tip is brass and has a larger opening and a black plastic cap. 1. Follow Pressure Relief Procedure, page 6. 2. Lock trigger safety. 3. Without holding your hand over the spray tip (A), pull back the quick coupler ring (B). Remove the current tip. Install a different tip. Push quick coupler ring back into place. B ti5440a A CAUTION To avoid the high pressure blowing the o-ring out of the quick coupler, never operate the pressure washer without a tip securely mounted in the quick coupler. 309286K Shutdown, Flushing and Storage 10 309286K Shutdown, Flushing and Storage Short-term Storage (less than 30 days) • Before you store the pressure washer overnight or transport it, disconnect the water supply and CLOSE the fuel supply valve. • After each use, wipe all pressure washer surfaces with a clean, damp cloth. Long-term (more than 30 days)/Winter Storage • Do not store unit outside where it can be exposed to rain, dirt or adverse weather conditions. • Do not expose pressure washer to freezing temperatures or allow water to freeze in pressure washer components which could cause the pump to lock-up. If this happens, allow the pump to thaw naturally in a WARM ENVIRONMENT. Do not attempt to speed up this process by pouring warm water on the pump. T...
