28 totalWhat type of oil should I use in the DeWalt 3400 PSI Pressure Washer?
You should use DP70 oil for optimal performance. The oil capacity is 14 oz (414 ml), and you should check the oil level before starting the machine.
What should I do if the engine will not start?
First, ensure there is fuel in the tank and check the oil level, adding oil if necessary. Verify that the spark plug wire is attached and confirm that the engine's ON/OFF switch is in the 'ON' position. If the problem persists, refer to the error codes section for additional troubleshooting.
How do I assemble the handle on the pressure washer?
Slide the handle assembly onto the frame, align the holes, insert saddle bolts, and secure with knobs, tightening until snug. Then attach the top handle to the handle assembly using the same method.
What is the maximum water temperature this pressure washer can handle?
The water supply temperature should not exceed 100°F (37.8°C) for proper operation.
What does Error Code 2 mean?
Error Code 2 indicates low oil. You should check the oil level and add DP70 oil if necessary before attempting to start the engine again.
How do I address the issue of no or low pressure?
Check for a clogged nozzle and clean if necessary. Ensure the water supply is adequate (at least 5 GPM at 20 PSI) and inspect the high-pressure hose for leaks or damage.
