Maintenance - Sealey PC2950.V5 Instruction Manual

Advertisement

5.2
Primary checks. Check that the inlet filter is clean; pump delivery and pressure will be reduced if blocked. Never use the machine
without a filter (which is fitted inside the hose connector, see Item 4 in Section 3 'Contents'). Ensure that the water supply, high
pressure hose and gun are correctly connected, and that air can freely circulate around the washer.
5.3
Connection to power supply. The washer should be used in conjunction with an RCD safety cut-out device as indicated in fig.9.
( An RCD can be purchased from your local Sealey dealer.) Plug the RCD into the mains supply and plug the washer into the RCD.
Test the RCD in accordance with the RCD instructions.
5.4
Operating the machine. Before switching on ensure that the lance is not directed at people, objects or animals prior to being
directed at the object to be cleaned. It is recommended that the trigger is depressed before switching on the unit before every use.
This reduces the back pressure and amperage draw which prevents fuses blowing. Switch the machine on by pressing the button
marked 'I' as shown in fig.10 above. Release the safety catch (see fig.7B). Hold the spray gun firmly to counteract the recoil caused
by the high pressure of the water. Point the lance at the object to be cleaned and fully depress the trigger. When the trigger is
released the motor will automatically switch off.
5.5
Rotorblast nozzle. The nozzle is non-adjustable. Do not attempt to turn it or disassemble it or your warranty may be void. Keep the
nozzle 150 to 200mm from the surface being cleaned.
5.6
Using detergent. Use only detergents approved for use in pressure washers.
5.6.1
Remove the lance that is attached to the gun and attach the soap dispenser as indicated in fig.11.
5.6.2
Remove the bottle and check that the tube is not blocked.
5.6.3
Fill the bottle with detergent suitable for use with a pressure washer and re-attach it. As you operate the trigger the detergent will be
automatically mixed with the water and discharged through the nozzle.
5.6.1
Dirt is dissolved by applying detergent to the dry surface. On vertical surfaces, work from the bottom upwards.
5.6.2. Leave the detergent to act for 1 - 2 minutes, but DO NOT allow the surface to dry out.
5.6.3. Re-attach the lance and wash down the surface with clean water.
5.7.
When washing is completed.
5.7.1. Switch the power supply off by pressing the button marked 'O' as indicated in fig.10.
5.7.2
Turn off the water supply tap.
5.7.3
Discharge residual pressure by pressing the trigger until no more water comes out of the nozzle.
5.7.4. Engage the trigger safety catch and unplug the machine from the electrical mains power supply.
5.7.5
Wipe the machine clean and dry and store in a clean, safe, dry, childproof location.
NOTE: a) DO NOT leave motor switched on for more than 15 minutes without operating trigger.
b) If the water pressure drops (i.e. someone else using the same water supply), the washer will not operate correctly. Immediately
switch off the motor and wait until the pressure is restored.
c) Should the motor stop and fail to restart, the built in thermal cut-out may have tripped. Check to ensure that the washer is
connected correctly to electrical and water supplies (also see Section 7 Troubleshooting). Wait 5 minutes for the cut-out to reset
and re-start the motor. If the motor continues to cut out contact your authorised service agent.

6. MAINTENANCE

WARNING! Ensure the pressure washer is switched off and unplugged from the electrical power supply and turned off at the
water supply tap before proceeding.
