Water seal on
saw head:
In the saw arm, there is a swivel to feed the water into the centre of the
spindle and further to both sides of the blade flange. Two seals seal off
the water which is fed through the spindle quick disconnect screw, and
on through the pull stud at the front of the spindle. Beside the screw there
is a small hole. (see picture on next page for reference)
Important! If water comes out of that hole while the water is switched on, this is an
indication that the seals must be replaced. Please contact your dealer for service. The
swivel should be checked every day. If the seals are not replaced in time, water may enter
the saw arm transmission and gearbox, which may cause the transmission to seize or cause
irreparable damages. Please take care to replace the seals every month.
Procedure to replace
water seals:
1. Use two screwdrivers to pry out the seal cartridge as shown in the
picture below. The seal arrangement is shown in the bottom picture.
Please note the wear sleeve on the rotating shaft.
2. Replace the worn seals with new ones and grease seals with a water
resistant grease.
3. Use a plastic hammer to lightly tap the seal cartridge in place again.
4. If the wear sleeve needs to be replaced, the wear sleeve can be pulled
off using a special tool, Part No. 65420100. The new wear sleeve should
be installed flush with the clamp screw as shown in the picture below.
