Start-Up Procedure; Shutting Down - DeWalt DP2800 Guide D'utilisation

• NEvER turn water supply off while pressure washer engine is
running or damage to pump will result.
• DO NOT stop spraying water for more than two
minutes at a time. Pump operates in bypass
mode when spray gun trigger is not pressed.
When the temperature inside the pump rises
too high the thermal relief valve (T) will open
and release a gush of water in an effort to lower
the temperature inside the pump. The thermal
relief valve will then close. If pump is left in bypass mode for
more than two minutes internal components of the pump can
be damaged.
