Pace Hydraulic Powered Pressure Washer User Manual

Hydraulic Powered Pressure Washer
SAFETY INSTRUCTIONS
1. Water is discharged from this machine at very high pressure. Never point the spray wand at persons or any part
of the human body. High pressure water may result in severe personal injury.
2. Never tie open the spray gun trigger or start the machine with the spray gun unattended. High-pressure flow
could cause the gun and wand to fly around causing personal injury or property damage.
3. Do not run acids, petroleum-based solvents, highly chlorinated materials or insecticides through this pump.
Damage to internal parts could result. Use only detergents formulated for use with pressure washers and follow
the manufacturer’s instructions.
4. When using this machine, wear goggles or a face shield to protect eyes from spray, chemicals or back-spattered
materials.
OPERATION
1. Fill tank with water or turn on water supply. (Pump must have positive head pressure.)
2. Hook up hydraulic hoses.
3. With machine at idle, engage hydraulics, then increase engine rpm until desired water psi is reached.
4. Grasp gun firmly. Point wand at object to be cleaned and squeeze the trigger. Experimenting with the distance
the nozzle tip is held from the surface to be cleaned is recommended. The closer the tip, the greater the impact;
however, as the tip is moved farther back a larger area can be covered. Avoid opening and closing the trigger
gun in rapid succession, as this is hard on the unloader valve.
5. Pump must be horizontal when operating.
MAINTENANCE
1. Before shut down, wash off the pump and orbit motor to rinse off any foreign material.
2. Wipe down hose and coil for storage. Inspect hose daily for cuts or abrasions.
3. Change pump oil every 200 hours. Check oil level daily and “Top Off” as required. Use 30-weight non-
detergent oil.
PROTECT AGAINST FREEZING TEMPERATURES
1. Remove suction hose from water supply and place hose in a container of ethylene glycol anti-freeze.
2. Start the machine. When you see anti-freeze coming from the nozzle, trigger the gun a couple of times. This
will allow the unloader valve to be purged.
NOTE: After water is purged from the system, anti-freeze can be captured for reuse.

Summary

Safety Instructions

High-Pressure Water Hazards

Water is discharged at very high pressure. Never point the spray wand at persons or body parts.

Gun Handling and Operation Safety

Never tie open the spray gun trigger or start the machine unattended to prevent injury.

Chemical and Solvent Restrictions

Do not run acids, solvents, or chlorinated materials through the pump to prevent internal damage.

Eye Protection Requirements

Wear goggles or a face shield to protect eyes from spray, chemicals, or back-splattered materials.

Operating the Pressure Washer

Water Supply and Hose Connection

Fill tank with water or turn on water supply. Pump must have positive head pressure.

Engaging Hydraulics and RPM Adjustment

At idle, engage hydraulics, then increase engine rpm until desired water psi is reached.

Spray Gun Trigger Control

Grasp gun firmly, point wand, and squeeze trigger. Experiment with distance for cleaning.

Pump Operation Orientation

The pump must be horizontal when operating.

Maintenance Procedures

Pre-Shutdown Cleaning

Before shut down, wash off the pump and orbit motor to rinse off any foreign material.

Hose Inspection and Storage

Wipe down hose and coil for storage. Inspect hose daily for cuts or abrasions.

Pump Oil Maintenance

Change pump oil every 200 hours. Check oil level daily and top off with 30-weight non-detergent oil.

Protecting Against Freezing

Anti-Freeze Procedure

Remove suction hose, place hose in anti-freeze container, start machine to purge.

Troubleshooting Pressure Washer Issues

Pump Produces No Flow

Check for pump priming, nozzle PSI mode, or a plugged nozzle.

Pump Loses Prime

Investigate air leaks, blocked suction lines, clogged strainers, or unloader valve issues.

Chattering Noise & Pressure Fluctuations

Check for incorrect nozzles, restricted intake, or dirt in check valves.

Low Pressure at Nozzle

Ensure adequate water supply, correct line size, and sufficient water level.

Unit Makes Knocking Noises

Adjust unloader valve pressure setting or check hydraulic system relief valve.

Unit Makes Chattering Noise

Adjust unloader valve or ensure hydraulic relief valve is set correctly.

Unit Doesn't Develop Good Pressure

Check nozzle, check valves, hydraulic motor oil flow, or vehicle relief valve settings.
