Raising And Lowering - Craftsman 351.215680 Operator's Manual

Feed Belt Speed Control Knob
CAUTION: Change speeds only while machine is running,
The feed belt speed control knob is located in the center of
the front panel of the sander. To increase belt speed, rotate
the knob counterclockwise.To decrease belt speed, rotate the
knob clockwise.
• Stock can be removed more quickly by using a fast speed,
but the machine works much harder, and the wood is left
with a rougher finish. Slowing the speed will lightenthe
load of the sander, and make the finish better, but it will
increase the sanding time.
• Reduce speed for wider boards and hardwoods.
Feed Belt Speed Indicator
Indicates the belt speed in feet per minute.
Switch Lock
Refer to Figure 10.
The sander can be locked from unauthorized use by locking
the switch.To lock the switch:
• Turn the switch to OFF position and disconnect saw from
power source.
• Pull the key out. The switch cannot be turned on with the
key removed.
NOTE: Should the key be removed from the switch at the ON
position,the switch can be turned off but cannot be turned on.

ADJUSTING TRACKING AND TENSION ON
THE FEED BELT
Refer to Figure 12.
NOTE: With a new belt, it is not unusual for one side of the
belt to be tighter than the other to make the belt track.
Frequent adjustments are normal for the first few hoursuse to
allow for belt stretch. Adjustmentsto belt tracking can also
affect belt tension.
Belt shouldride cantered on the drive and idler rollers.The
drum sander is shipped with the tracking and tension properly
adjusted. However, if adjustment is necessary:
Tensioning
NOTE: When adjustingbelt tension, tighten or loosen both
bolts the same amount to avoid affecting belt tracking.DO
NOT over tensionthe belt. Excessive tension will cause pre-
mature wear of belt, bearings and overload the motor.Listen
for motor lead speed changes when adjusting belt tension.
NOTE: Adjustments to belt tension can affect belttracking.
Frequent adjustments are normal for the first few hoursuse to
allow for belt stretch.
• The belt needs adjustment if it slips on the rollers during
sanding operations.
• Loosen all four socket head bolts (A).
• Loosen hex nut.Turn both hex head bolts (B) clockwise '/,
turn and check tension. Repeat until the feed belt is tensioned
properly. Tighten hex nutsto secure bolts in position.
• Tighten all socket head bolts.
RAISING AND LOWERING THE FEED TABLE
Refer to Figure 11.
• To raise the feed table, turn the handwheel clockwise.To
lower, turn bendwheel counter-clockwise.
NOTE: Each turn of the handwheel will increase or decrease
the height of the table by '/_6"
• Stock removed settings:
1/,turn - For material removal (V=")
% turn - For general finishing (V,_")
'/,_turn - For fine finishing passes
On the last finishing passes, pass the board throughtwo or
three times to level hard spots or knots.
• Reduce depth of stock removal for wider boards and hard-
woods to prevent tripping overload protection.
