REMOVING PLANER KNIVES

1.  Unplug the machine and put the power switch in the 

OFF position until all adjustments are complete.
2.  Remove the jointer fence assembly.
3.  Raise the cutterhead guard and

 remove the guard 

(#207) to get full access to the cutterhead and knives.
4. Loosen the Lockbar (#102) in the block with the 10mm 

hex head Lockbar ‘Grub’ Screws (#101). FIG. 36.

5. R

emove the lockbar FIG. 36, A and the attached planer 

knife (B) from the cutterhead (C).
6.  Clean all surfaces of the cutterh

ead and planer knife 

lockbar.

INSTALLING THE PLANER KNIVES

7.  Install the new planer knife onto the back of the lock-

bar. Make sure that both positioning pins on the lockbar 

fit into the matching holes on the plane

r knife FIG. 37. 

NOTE:

The 25-010 planer blades (#105) are reversible! Both 

front and back edges are sharpened. Just flip to change.

8.  Place the lockbar with the mounted knife back into the 

cutterhead.  Make sure that the lockbar is centered in the 

cutterhead block.  

NOTE: 

Take care that the knife does 

not slip off of the two pins during this step.
9.  

Tighten the four Lockbar Grub Screws to secure the 

set knives in the cutterhead.   

NOTE: 

 To prevent distor-

tion of the lockbar and knife, start with tightening the grub 

screw in the center, then move out to the side screws.

SETTING THE PLANER KNIVES - method 2

This method involves using a ruler, and a piece of wood or 

aluminium straight edge, preferably one with a wide body.
1.  Place the straight edge at either side of the cutterhead, 

resting on both feed tables.

FIG. 34.

2.  Slowly turn the cutterhead by hand, in the direction of 

the cutting knives. If the planer knives are set correctly, the 

end of the straight edge is moved forward 1/8” to 3/16”. 

FIG. 35. If 

the straight edge moves less than 1/8”, the 

knives are set too low. If it moves further than 3/16”, they 

are set too high. 
3.  Se

e Page 17, steps 2-4, for

 information on how to 

loosen the retaining screws to make knife adjustments.
4.  This procedure must be performed at both ends of 

the knife in the cutterhead. The straight edge movement 

measurements must be exactly the same at both ends. 
5.  Then, the same measurement must be set to the other 

two knives in the cutterhead to ensure that all 3 knives are 

set at the same height.

Continued  from page 17

                               Wear gloves when changing the knives 

to avoid the risk of personal injury by cuts that may result 

from touching the sharp edges! 

10.  Perform the same procedure, steps 4-9, on the two 

remaining planer knives in the cutterhead.
11.  Once all three knives are replaced, they must be all set 

at the sam

e height. See page 17 &18 for 

instructions on 

how to set the planer knives.

12.  Plug in the power cable when you are ready to 

resume jointing and planing.
