Lance/Cleaning Gun Precautions
The lance is to be operated only by trained operators.
Please read the following instructions before
attempting to operate.
Maximum operating pressure: 3000 PSI.
Make sure the maximum operating pressure does
not exceed the equipment’s maximum operating
pressure rating.
If any part of the body comes in contact with the
pressurized spray stream, immediately contact a
physician.
Table 4-1:
Serious Injury or Death May Result.
DO NOT:
Safety Should Always Be Observed.
DO:
Aim the lance gun at any person or any part of the body.
Fluids under high pressure can penetrate the skin and
result in severe injury, amputation, or death.
Develop a habit of shutting off the pressure at the lance
gun and hose before attempting to remove the nozzle,
gun, or any part of the gun, or when the lance gun is not
in use.
Place hands or any other portion of the body in front of
the spray nozzle.
Carefully check and tighten all connections regularly.
Make sure all connections are secure and leak-proof.
Alter equipment in any manner. (If repairs are
necessary, use only genuine factory repair parts
available from Super Products.)
Make sure trigger is operating properly.
Operate the lance gun without the trigger guard
attached.
Adapt a secure body stance prior to and during lance
gun operation to aid in control of the high reactionary
force of the lance gun.
Exceed the maximum operating pressure. Keep lance gun clean to allow for a positive grip and
safe operation.
Leave the equipment under pressure and unattended at
any time.
Relieve water pressure by shutting off the water supply.
Actuate the lance gun trigger until water stops flowing.
Use if the hose if damaged or weakened. Make sure the lance gun is insulated properly when
used in a dangerous environment.
Operate the lance gun if there are any leaks from the
packing, fittings, or hoses.
Never exceed the maximum operating pressure. Make
sure the relief valve is operating properly.
Tape or otherwise lock the lance gun trigger into the ON
position.
