REGULAR CHECKS & OPERATING TIPS
•Check all oil levels:
oHonda & KOHLER engine oil level –check. Use
manufacturer’s recommendations.
oGearbox oil level (sight glass should be half) SAE80W90
Gearbox oil.
oPump oil level (sight glass should be half full) SAE 15W40 /
SAE 10W/40 SAE 30
•Water Supply - Low water supply can cause cavitation and/or pump
running dry casing expensive pump failure. Always check to ensure
supply is:
oUninterrupted
oPressure is good (10 PSI / 30 LPM)
oThere are no kinks in supply hose
oFittings are in good condition and not leaking
•Worn Jets - System will function okay, but with oversized, worn
jets, the pressure will be much lower and cleaning ability reduced.
Always use new jets to check operation efficiency
•Operating Pressure - Check operating pressure to see if it within 10%
of units specified operating pressure. If pressure drops over time it
may indicate general wear and tear and a service is recommended.
•Air Leaks - Especially in suction to pump hoses. Repair immediately if
found. Check for cuts & abrasions
•Lance & Gun Assemblies - Check for damage and leaks. If
leaking/damaged DO NOT use & get repaired/replaced immediately
•Filters - Check to ensure filters are clean, filter heads/tops are not
cracked, seals are not worn and sealed air tight and mesh tube is
unblocked
•Safety - Ensure safety protective gear is used and in good state of
repair.
•Prolonged by-pass - Leaving the unit in prolonged by-pass (machine
is switched on but trigger is not depressed) can cause excess wear &
tear due to water over-heating which damages seals. Portable units
have a safety mechanism built-in to prevent damage:
oAutomatic dumping of hot water when water temp rises
above 63 deg C

9
•Worn By-Pass Valves - Soft-Acting By-Pass valves should NOT store
high pressure water in hose down-stream between by-pass valve and
high pressure gun.
•Water Leaks - Excessive hammering can cause damage. Fix leaks
when they occur
•Water Condition - Ensure water source is clean (potable water). Not
recycled water or bore water which can damage pumps.
•Tyre Pressure –Check Trailer mounted units only
•Mechanical Brake System (Trailers) –Check all bolts and nuts –
tighten if necessary
REMEMBER –CHECK FOR ANY HIGH PRESSURE
WATER OR OIL LEAKS

MAINTENANCE SCHEDULE AND TIPS
MAINTENANCE SCHEDULE:
This maintenance schedule does not include the Engine Maintenance
Schedule. Please refer to Honda Operators Manual or the Honda website or
Kohler Operators Manual or Kohler website.

11
MAINTENANCE TIPS:
USE THE FOLLOWING GUIDE WHEN CONSIDERING MAINTENANCE:
Always test your machine using a new high-pressure nozzle - correctly sized
for set-up pressure and flow.
Before you start pulling pumps apart, do obvious checks first:
•Worn /blocked Jets
•Air Leaks
•Engine Speed (Not too low)
•Suction Filters (Blocked?)
•Water supply volume (Not too low)
Remember to check filters regularly (if fitted) and clean under running
water.
The correct procedure for replacing the filter mesh is to first put the mesh into
the cup after rinsing under running water and then screw it back onto the
filter head.
TRAILERISED UNITS ONLY
Correct procedure of replacing the filter cartridges
•Always put the filter mesh tube into the ‘head’ first ensuring it is
square and tight.
•Now screw on the cup part of the filter.
Doing it the opposite way may result in a crushing of the filter mesh!

slippery surfaces and by- standers!
•Never allow untrained adults or minors use of the
equipment.
•Never use the machine if there are any leaks on the high
pressure delivery side of the pump.
• R ead and observe the manufacturer's instructions if chemicals are
being used.
•The “recoil”on larger machines is positive - lean forwards and brace
yourself to take it up!!!
•NEVER HIGH PRESSURE BLAST THE FOLLOWING: any electrical
components, motors / switchgear or electrical boxes as injury or
death may result.
•Never water blast any fuel caps or oil caps and water can get into
breather holes and contaminate fuel or water. Never blast water
directly into seals / bearings on shafts where water penetration
would be detrimental.
•NEVER WATER BLAST: fragile items / surfaces that may be
damaged by high velocity water. Always carefully test on a small
area first.

13
•ALWAYS WEAR PROTECTIVE GEAR (PPE) i.e. head, face, eye
protection, wet weather gear, boots and gloves - which is
particularly important where hot water or aggressive chemicals are
being used or where whet sandblasting is used.
•Keep hands, feet and hair away from all moving parts.
•Never leave machine running unattended.
•EXTREME DANGER - never adjust engine speed (RPM) or safety
by-pass valve in an attempt to increase pressure!
•Barricade off immediate work area - restrict access - erect hazard
warning signs.
•Prior to high pressure water blasting, check location’s level of
emergency /first aid.
EXPLOSION RISK –Petrol is explosive! Never re-fuel when the engine is hot –
Petrol fumes can ignite and explode leading to severe burns and even death!
Do not smoke when re-fueling! Keep away from fire, sparks, heat or static
electricity.
WARNINGS & SAFETY PRECAUTIONS SPECIFIC TO THIS MACHINE:
•Never re-fuel when the engine is hot –Petrol fumes can ignite and
explode leading to severe burns and even death!

EXTREME DANGER!
•Beware of HOT engines (particularly Mufflers)
•Store fuels in approved containers in a well ventilated
area away from heat.
•Ensure enough air flow around engine to keep it
cool and to void any fumes / exhaust gasses.
•Use Specified and approved Personal Protection
Equipment (PPE) for High Pressure Cleaners. This is a
High Performance High Pressure Cleaner.
An injury by high pressure water jets
can be serious!
In the event of any water jet injury:
•Seek medical attention immediately –do not delay
•Inform the doctor of the cause of the injury
•Tell the doctor what type of project/task was being performed at the
time of the injury making special note of any chemicals that were
used and the quality of the water is important in deciding on initial,
empiric antibiotic treatment and broad-spectrum intravenous
antibiotics should be administered. Cultures should be obtained.
