W1754 20" Planer With Mobile Base
OPERATIONS
Adjustment Height Range: .................. 0.002"–0.020"
The height of the bed rollers will vary, depending on the
type of material you intend to plane, but as a general
rule keep the roller height within 0.002"–0.020" above the
table (Figure 13). When planing rough stock, set the roll
-
ers high to keep the lumber from dragging along the bed.
When planing milled lumber, set the rollers low to help
minimize snipe.
To ensure accurate results and make the adjustment pro
-
cess quicker and easier, we recommend using a Model
W1218 Rotacator (see Page 21) to gauge the bed roller
height from the table. If a Rotacator is not available, a
straightedge and feeler gauges can be used, but extra
care must be taken to achieve satisfactory results.
Note:
Misaligned bed rollers can cause workpiece chat-
ter, a washboard surface, uneven workpiece feeding, or
binding. This is the most common cause for poor planing
results.
To adjust the bed rollers, do these steps:
1. DISCONNECT THE PLANER FROM POWER!
2. Lower the table to give yourself at least 4" of work-
ing room below the cutterhead.
3. Using a 3mm hex wrench, loosen the locking set
screws (see
Figure 14) above the roller adjusters (4
total).
4. Raise or lower the rollers by rotating the roller
adjusters to reach your desired height.
5. Verify both sides of the bed roller are at the same
height in relation with each other, side-to-side, and
to the table surface, and lock them in position with
the locking set screws.
6. Double check the roller heights to make sure they
did not move when you locked them (if they did,
repeat the procedure).
