SAFETY GUIDELINES / DEFINITIONS

This manual contains information that is important for you to know and understand. The content relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. Please read this manual carefully and follow all instructions.

ALWAYS REFER TO THE MANUALS SUPPLIED WITH THIS UNIT

SAFETY PRECAUTION

•  Do not operate this pump without first reading the complete user manual. Failure to do so may result in accidents or unnecessary equipment damage.
• Check the oil level in the crankcase shell. The use of S2G200 gear oil is suggested. The oil level must reach at least half the oil mark on the indicator. Never operate the pump before lubricating oil has been checked. 
• When stopping, always cut power to the pump first, then shut off the • water source. 
• Pump outlet pressure must be set to appropriate levels. Do not exceed the maximum rated working pressure at any time. 
• Install a suction filter with a minimum mesh size of 40 mesh/inch on the inlet pipe to prevent impurities and debris from entering the pump.

FEATURES AND USE

The Hooker Pumps Pressure Washer is powered by a brushless DC motor, delivering field-proven performance at flow rates of 1 to 5 GPM and pressures of 250 to 1,200 PSI. Built to the highest quality standards for marine and industrial environments where reliability is non-negotiable

APPLICATIONS

• Portable restroom washdown
• Air-conditioning fan and enclosure wash
• Truck and equipment cleaning
• Surface cleaning
• Other uses requiring high-pressure water
• Mobile Detail
• RV Wash
• Boat Wash
• Maintenance Vehicle

PRESSURE WASHER PUMP TECHNICAL PARAMETER

TECHNICAL INFORMATION

On-demand power. The Hooker Pumps Pressure Washer system activates the moment you pull the trigger — and shuts down the instant you release it. No idle run time, no unnecessary battery consumption. The brushless DC motor and pump run only when work demands it, extending service life and maximizing efficiency on every job.

PREPARATION

• Before use, inject lubricating oil (ISOVG 68-150) into the crankcase until the oil level reaches half. Replace the red oil plug with an oil dipstick. Failure to replace the oil plug voids the manufacturer’s warranty.
• Connect the water outlet pipeline, water inlet pipeline, suction filter, and bypass pipeline. Verify that all fasteners and pipeline joints are properly secured before startup.
• Install a filtering device of no less than 40 mesh/inch at the end of the inlet pipe to prevent debris from entering the pump and affecting normal operation.

STARTUP AND OPERATION

• The general unloading valve is pre-adjusted to rated pressure — no re-adjustment is required under normal conditions.
• Due to the limited water absorption performance of the plunger pump, keep the liquid level in the water tank no lower than the pump’s installation height.
• When using a water tank as the supply source, prime the pump by filling water through the inlet pipe while the spray gun trigger is open to exhaust air from the pipeline. Once the pump operates normally, place the inlet pipe in the tank — ensuring the water level remains above the machine base — and fit the inlet pipe with a filter.

If no water discharges within 30–60 seconds of startup, fill the pump inlet pipe and inspect the inlet pipeline for suction issues.

Do not allow pump pressure to exceed the specified rating. Reduce pressure immediately if the rated pressure is exceeded to prevent pump overload and damage.

Maximum dry-run (dehydration) operation time: 90 seconds. 

Always fill the crankcase with oil before operation. Use Shell S2G200 gear oil. Operating without oil will cause irreversible pump damage.

Note: It is normal for the movement seal to show minor oil or water droplets during operation, provided the water drip rate does not exceed 1 ml/min (approximately 10 drops/min).

SHUTDOWN AND STORAGE

• Before shutting down, power off the pump and wipe all external components clean.
• If storing in temperatures below 0°C, inject antifreeze (e.g., 75% alcohol solution) into the pump and accessories.
• To inject: start the pump and draw antifreeze through the inlet until it discharges from the spray gun, then shut off.
