Karcher Pressure Washer Suction Cover With Sv5

1. Tools needed

All you’ll need is a Phillips screwdriver, a T15 screwdriver and some long-nosed pliers.

To remove the suction cover, first, eliminate all power.

2. Remove wheels and casings

Then, remove the wheels.

Remove plastic outer casing

You need to remove all the screws holding the plastic outer housing shell in place. These might be tightly secured, so take your time.

Remove detergent tank holder

Then, remove the four screws holding the detergent tank holder in place at the bottom. You can then remove the pipe hose and the tank away from the pressure washer.

There will be two more screws that need to be removed. One on either side of the yellow housing.

3. Remove motor and old suction cover

Remove the detergent suction pipe hose and lift the motor up and out.

Remove suction cover

To remove the suction cover, twist it up and then away from the motor unit.

Remove the fine filter with a pair of lone nose pliers.

4. Install new suction cover

If needed, lubricate the seal with the provided silicone grease and replace the O-ring if faulty.

Then, push in your new fine filter until you hear it click.

You can then install the new suction cover as shown here.

5. Re-assemble casing

You can place the motor back in the casing and reattach the detergent suction pipe hose. Then, pop the plastic housing back on. For this to attach securely and easily, you may need to unscrew the four screws with a Phillips screwdriver on the black casing at the bottom of the handle.

Then, go ahead and re-screw all the screws back into the plastic outer housing. And if you unscrewed the four screws on the bottom of the handle, also re-screw these in.
