REGULAR CHECKS & OPERATING TIPS
•
Check all oil levels:
o
Honda & KOHLER engine oil level
–
check. Use
manufacturer’s recommendations.
o
Gearbox oil level (sight glass should be half) SAE80W90
Gearbox oil.
o
Pump 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:
o
Uninterrupted
o
Pressure is good (10 PSI / 30 LPM)
o
There are no kinks in supply hose
o
Fittings 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:
o
Automatic dumping of hot water when water temp rises
above 63 deg C
