ble the hose, gunjet and nozzle. Roll up the hose

USER-MAINTENANCE INSTRUCTIONS
1. The pump has an oil bath in the pump
transmission. Check to oil before every use to
insure that there is sufficient oil and that the oil is
not discolored. Remove the dip stick. The oil level
should be within the flat area on the dip stick. Use
synthetic oil, 5-W50. Change the oil after the first
50 hours of operation and every 200 hours there-
after.

the filter as necessary.
3. Check the unit for water leaks. Any leak in the
inlet garden hose, hose connection, gunjet, lance,
or nozzle will allow air to get into the pressure
washer pump and cause malfunction and damage.
Leaks will also cause the pressure switch to cycle,
confusing the auto on/off switch. Fix any leaks
immediately.
FREEZE PROTECTION
Pressure washers equipped with the Kränzle
pump can be run dry without damage. To protect
your pump from freeze damage, disconnect the
high pressure hose and water hose from the pump
and run the pressure washer for thirty seconds or
until all the water is ejected from the pump. If you
have a hot water pressure washer, or a pressure
washer equipped with a float tank we recommend
the use of antifreeze to protect hot water coil from
freezing. Simply hook up suction hose from inlet
water connection to container of anti-freeze. Run
the unit long enough to fill the coil with the
anti-freeze mixture. The mixture should be full
strength - but no less than 50% solution.
REMEDY
Replace nozzle
Disassemble, reseal and
reassemble
Clean and check frequently
Check and replace packing
Check water supply for sufficient
flow and obstructions in inlet
filter
Check and replace valves
