SENATOR G2 MANUAL - HIGH PRESSURE CLEANER
Water Supply
Run a hose from the water source to the unit water inlet.
Use the largest diameter, shortest length hose possible. A
3/4” I.D. Inlet hose is the minimum recommended size. An
appropriate backflow prevention device should be used to
comply with all local codes and ordinances.
Dirt and debris in the water supply can cause excess pump
wear, clog the unit filter, nozzles and reduce performance.
Do not use water from ponds, lakes or other sources that
may be contaminated.
Fill the OPTIONAL water tank prior to starting the unit (If
Applicable).
The OPTIONAL water tank is equipped with a:
• Low water level shut-off (If Applicable) to prevent
pump damage from insufficient water. This will shut
OFF the engine when the tank water level falls below a
predetermined level.
• Float valve to shut-off inlet water when the tank is full,
preventing water spillage through the tank vent.
Warm water can be used for improved cleaning. Do not
use water hotter than 60°C. When using warm water, use
appropriate personal protective equipment to reduce the
risk of burns.
When using in cold weather, use precautions to prevent
water from freezing in the pump. This can damage the
pump.
Hose Set-Up
Use care when routing hoses. Routing hoses over rough
surfaces, sharp edges, crossing hoses, etc. can damage
the hose jacket. Keeping the unit hose on the reel(s) will
help to minimize hose damage.
Operating Instructions
CAUTION
Always wear eye protection to protect your eyes
against dirt and other foreign objects. Always wear
appropriate personal protective equipment for the
work environment.
Never operate the unit without the hose attached to
a spray gun. Hose can whip, causing striking injuries
and spray can penetrate skin and cause serious
injury.
High pressure fluid can inject under skin resulting
in serious injury, including amputation. do not direct
spray at people or animals. do not operate unit above
pressure rating or 60°C (inlet water temperature).
This increases the risk of injury, including burns, and
damage to the unit. One person must control the unit
process and water flow.
Always use appropriate personal protective
equipment while handling and using high pressure
cleaning equipment. Appropriate personal protective
equipment always includes safety glasses and
gloves, and may also include equipment such as latex
or rubber gloves, face shields, goggles, protective
clothing, respirators, and steel toed footwear.
Follow operating instructions to reduce the risk of
injury from whipping hoses, high pressure liquid
injection, carbon monoxide and other causes.
1. Make sure that machine and work area is properly set
up and that the work area is free of bystanders and
other distractions. If the unit is located remotely from
the point of use, another person may be located at the
unit.
2. Attach the gun to the high pressure hose via coupling
system.
3. Attach the hose to the high pressure outlet on the front
of the unit.
4. Turn the battery isolator switch ON (Figure 11) and
confirm the Emergency stop button is in the out
position (rotate button clockwise).
5. Attach your water supply hose to the low pressure
water inlet port on the front of the machine. Confirm
that the water supply is turned. Never start the engine
without the water supply turned ON. This can damage
the pump.
6. Ensure fuel valve is in the OPEN position before
starting the machine, when not in use CLOSE the fuel
valve as pictured (Figure 11).
