3. When pressure washing, detergents are only dis-
pensed when wash wand nozzle is in the low pres-
sure position. Pull the nozzle forward to the low
pressure position to dispense detergent.
4. During operation, the detergent application rate can
be adjusted by turning the sleeve on the detergent
injector. Counter-clockwise increases the amount of
detergent, clockwise decreases.
5. When detergent application is complete, remove
the strainer from the detergent, place into a bucket
of clean water and flush the system of any deter-
gent.
Maintenance Instructions
WARNING
Before performing any maintenance, engine switch
should be in OFF position and spark plug wires
should be disconnected to prevent inadvertent op-
eration. Press foot valve or wand trigger to release
any fluid pressure in system.
Always wear safety glasses and gloves when per-
forming any maintenance to help protect against
drain chemicals and bacteria.
Cleaning
The hose should be cleaned as needed with hot, soapy
water and/or disinfectants. Do not allow water to enter
the engine or electrical system. Do not clean with pres-
sure washer. Wipe the unit down with a damp cloth.
Engine
Maintain the engine as directed in the engine opera-
tor’s manual supplied with the unit.
Pump Lubrication
Check the pump oil level prior to use. Place the jetter
on a level surface. Wipe any dirt and debris from the
area of the dipstick and remove the dipstick – check
the oil level. If needed, add SAE 30W non-detergent oil.
Do not overfill. Reinstall dipstick.
Change oil in pump after first 50 hours of operation
and every 500 hours of operation after that. With the
pump warm from operation, remove plug on bottom
of pump and drain oil into suitable container. Replace
plug. Fill with approximately 32 oz / 0,9 kg of SAE 30W
non-detergent oil using the checking procedure.
Gearbox Lubrication
Check the gearbox oil level prior to use. Place the jetter
on a level surface. Wipe any dirt and debris from the
area of the dipstick and remove the dipstick – check
the oil level. If needed, add SAE 90W gear lubricant. Do
not overfill. Reinstall dipstick.
Change oil in gearbox every 500 hours of operation.
With the gearbox warm from operation, remove plug
on bottom of gearbox and drain oil into suitable con-
tainer. Replace plug. Fill with approximately 8 oz /
0,2 kg of SAE 90W gear lubricant oil using the checking
procedure.
Preparing Pump for Cold Weather Storage
NOTICE
If the jetter will be stored under conditions
where the temperature is near or below 32°F / 0°C, the
jetter must be properly prepared. If water freezes in the
pump, it can damage it.
There are two methods for preparing the jetter for cold
weather storage. The first is to open all valves in the sys-
tem and use compressed air to force any water out of
the system. This can also be used to remove water from
the hoses.
The second method uses RV antifreeze (non-ethylene
glycol antifreeze). Do not use ethylene glycol antifreeze
in the jetter pump. Ethylene glycol cannot be used in
drainage systems.
1. Attach a 3’ / 90 cm section of hose to the inlet supply
valve and open valve.
2. Place the end of the hose into the container of RV
antifreeze.
3. Remove the nozzle from the end of the hose.
4. Start the jetter and run until antifreeze comes out of
the end of the hose.
