2. Using the 3mm Hex Key Wrench, turn both Screws clockwise
in increments of about one-eighth (1/8) of a revolution
(see
Figure on the right)
.
3. Check to see if the bearings are no longer loose by sliding the
Cutting Head Assembly up and down the Vertical Track
Assembly.
4. Repeat Step 2 and 3 above until both the lateral movement is
minimized and the vertical movement of the Cutting Head is
smooth.

Replacing the Cutting Head Bearings
If adjusting the bearings doesn’t work, you will need to replace two (2) round-shaped bearings
at the back, and two (2) v-shaped bearings at the front of the Cutting Head Assembly. The
chances of this are slim, so try the above adjustment before you replace the bearings.

Removing the Cutting Head
1. Loosen the Locking Knob on the Cutting Head.
2. Depress the Thumb Lever and raise the Cutting Head about 10" (254mm) above the
Horizontal Material Bar.
3. Locate the 10mm Hex Head Bolt on the bottom right side of the Vertical Track
Assembly.
4. Remove the bolt with a 17mm Wrench.
5. Remove the black Bumper and the Stop Block. Loosen the Locking Knob.
♦
Note: If the bumper is worn/damaged, you can replace it (see Section 47).

F.
Removing the Bearings
There are (3) three types of bearings and seven (7) black Flat Head Screws on the Cutting
Head Assembly:
1. Two (2) round-shaped type (white) plastic bearings on the back.
2. Two (2) v-shaped type (white) plastic bearings on the front
.
3.
One (1) brake-type v-shaped bearing in the middle on the front.
♦
Note: There are metal wear pads that are placed inside the v-shaped type
bearings and brake-type v-shaped bearing. These metal wear pads must
be assembled the same way in the new bearings and are necessary for
proper adjustment and braking of the Cutting Head Assembly.
1. Remove the Screws using a 2.5mm Hex Key.
2. Remove each Bearing and replace it with new Bearings.
3. Replace the Flat Head Screws.
4. Remount the Cutting Head Assembly onto the Vertical Track Assembly.
