Removing or installing planer blades

CAUTION. Always ensure that the tool is switched off and unplugged from the power supply before installing or removing blades.

Your planer is fitted with reversible blades.

Blades can be reversed when blunt. After both sides of the blades have been used they should be discarded.

NOTE. These blades cannot be re-sharpened.

Removing a planer blade

1.Using spanner (12), loosen the three clamping screws (8).

2.Slide the planer blade (6) from the slot in the blade barrel

(7) in which it is retained.

Installing a planer blade

1.Either turn over the planer blade (6) or replace it

if required.

2.Slide the good blade face up into the blade support block of the blade barrel (7).

NOTE. The ridge along the blade should be on the blade face on the opposite side to the clamping screws (8).

3.Tighten the clamping screws (8), ensuring they are tightened evenly.

4.Repeat for the second blade.

NOTE. Always change both blades at the same time, otherwise the resulting imbalance can cause vibration and shorten the blade and tool life.

CAUTION. When installing blades, first clean out all chips or foreign matter adhering to the blade barrel (7) and the blades themselves. Use blades of the same dimensions and weight, or the barrel will oscillate and vibrate causing poor planing action and possibly a machine breakdown. Tighten the clamping screws (8) carefully when attaching the blades to the planer. A loose clamping screw could be extremely dangerous. Regularly check to see they are tightened securely.

NOTE. Your planing surface will end up rough and uneven unless the blades are set properly and securely. The blades must be mounted so that the cutting edge is absolutely level, i.e. parallel to the surface of the rear base (10).

The examples below show proper and improper settings:

Correct setting

Front base (moveable shoe) (9)

Rear base (stationary shoe) (10)

Clean smooth cut

(a)(b)

Nicks in surface – as caused by the edge of one or all blades not being parallel to the rear base line.

Gouging at start – as caused by the edge of one or all blades not protruding enough in relation to the rear base line.

(a)(b)

Gouging at end – as caused by the edge of one or all blades protruding too far in relation to the rear base line.

(a)(b)
