NEVER turn water supply off before turning motor off. Serious damage could occur to the pump and/ or
motor.
WARNING! NEVER disconnect high pressure discharge hose from machine while system is pressurized. To
depressurize, turn motor off, turn water supply off and squeeze gun trigger 2-3times.
5. After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.
5. Storage
Do not store pressure washer outdoors.
Do not store pressure washer where it
might freeze.
TIPS FOR EXTENDING THE LIFE
OF YOUR PRESSURE WASHER
1. Never operate unit without water.
2. Pressure washer is not meant to pump hot water. Never connect to hot water supply – this will
significantly reduce life of the pump.
3. Using detergent other than others brand may cause damage to pump components (o-rings, etc.).This also
applies to chemicals such as bleach, dish soap, etc.
4. Never operate unit for more than one (1)minute without spraying water. Resulting heat buildup will
damage pump.
5. Before adjusting nozzle's pressure (high-to-low or low-to-high) release trigger. Failure to do so will reduce
life of o-rings in lance.

CLEANING AND MAINTANCE
Before any work on the machine itself, pull the mains plug. For safe and proper working, always keep the
machine and ventilation slots clean. In extreme working conditions, conductive dust can accumulate in
the interior of the machine when working with metal. The protective insulation of the machine can be
degraded. The use of a stationary extraction system is recommended in such cases as well as frequently
blowing out the ventilation slots and installing a residual current device (RCD). Please store and handle
the accessory(-ies) carefully. If the machine should fail despite the care taken in manufacturing and testing
procedures, repair should be carried out by an after-sales service centre for Maxpro power tools.

be collected separately and returned to an environmentally compatible recycling facility.
