or abuse. Inspect hose before each use. Check for cuts,
leaks, abrasions, bulging of cover, or damage or movement
of couplings. If any of these conditions exist, replace hose
immediately.
WARNING
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if clogged.
The tube should fit tightly on the barbed fitting. Examine the
