5.7.3 Fitting an accessory tool secured with a ‚Kwik lock' nut
CAUTION
Risk of breakage. Heavy wear (abrasion) may cause the ‚Kwik lock' nut to break.
▶ When working with the power tool, make sure that the ‚Kwik lock' nut doesn't come into contact
with the working surface.
▶ Do not use a damaged ‚Kwik lock' nut.
Note
The optional ‚Kwik lock' nut can be used instead of the standard clamping nut. Accessory tools (discs
etc.) can then be changed without need for additional tools (keyless system).
1. Remove the battery. → page 26
2. Clean the clamping flange and the quick-release clamping nut.
3. Check that the O-ring is in place in the clamping flange and that it is undamaged.
Result
The O-ring is damaged.
There is no O-ring in the clamping flange.
▶ Fit a new clamping flange with O-ring.
4. Fit the clamping flange onto the drive spindle (keyed fit to prevent slipping/rotation).
5. Fit the accessory tool.
6. Screw on the ‚Kwik lock' nut until it is seated against the accessory tool.
Note
The arrow on the upper surface of the nut must be within the index marks. If the arrow is not within
the index marks when the nut is tightened it will be impossible to release the nut by hand. In this
case, use the pin wrench to release the ‚Kwik lock' nut (do not use a pipe wrench!).
The name ‚Kwik lock' should be visible when the nut is screwed on.
7. Press the spindle lockbutton and hold it in this position.
8. Use the wrench to tighten the clamping nut or, respectively, rotate the accessory tool firmly by hand in
a clockwise direction until the ‚Kwik lock' nut is tight, and then release the spindle lockbutton. Remove
the wrench, if used.
