Operation & Troubleshooting
Spray Operation
The sprayer is operated by depressing the trigger. For continuous spraying pull the red plastic
locking catch backwards and locate onto the plastic lug, locking the trigger in the open position.
Flow Rate
The flow rate of the spray from the lance will reduce as the pressure in the sprayer reduces. The
pressure can be topped to a desired level using the orange pump handle.
Maintenance
After use, rinse the container then operate the pump with clean water to completely empty
the container and piston. At least once a year clean pump thoroughly, re-grease or lubricate
all moving parts.
Warning:
When assembling and servicing, carefully insert the pump piston
without forcing, so as not to damage the gasket.
Troubleshooting
The following table gives checks and actions that you can perform if your machine does not
operate correctly. If these do not identify/remedy the problem, contact your service agent.
