ADJUSTING TRACKING AND TENSION ON
THE FEED BELT
Referto Figure 12.
NOTE: With a new belt, it is not unusualfor one side ofthe
belt tobe tighterthan the other to make the belt track.
Frequent adjustmentsare normal for the first few hoursuse to
allow for belt stretch.Adjustmentsto belt trackingcan also
affect belt tension.
Belt shouldride cantered onthe drive and idler rollers.The
drum sander is shippedwiththe tracking and tension properly
adjusted. However, ifadjustment is necessary:
Tensioning
NOTE: When adjustingbelt tension,tightenor loosenboth
bolts the same amount to avoid affecting belt tracking.DO
NOT over tensionthe belt. Excessivetension will causepre-
mature wear of belt, bearings and overload the motor.Listen
for motorlead speed changes when adjustingbelt tension.
NOTE: Adjustments to belt tensioncan affect belttracking.
Frequent adjustments are normal for the firstfew hoursuse to
allow for belt stretch.
• The belt needs adjustment if it slips on the rollers during
sandingoperations.
• 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

ADJUSTING FEED TABLE PARALLEL TO DRUM
Referto Figure 13.
The drum sander isshipped from the factory with the drum
carriage set parallel to the feed table.However, if adjustment
is necessary:
•To check ifthe feed table is parallel withthe drum cylinder,
sand a wide board (preferably 12" or more in width x 2'
long) until itisfiat acrossthe totalsurfacearea on both sides.
•To do a quick check, draw pencil lines extendingacross the
width of the board at several places aloog the length of the
board.
• Reverse the board (end for end) and run the board through
the sander, if the sanding table is set properly, the drawn
lines will disappear. If the lines still appear on the left or
right side of the board, the table height must be adjusted.
• Disconnect tool from power source.
• Loosen the four socket head bolts.
•Turn both screw guides equallyto raise (counterclockwise)
or lower (clockwise) the table (one revolutionof screw
guide will move the table 0.125").
NOTE: When sandLngpieces wider than 18" and the drum is
not parallelto the table, a step or line will result.It isbest to
set the outboardside a few thousandths of an inch higherto
allowsanding a crown ratherthan a groove.
•Sandthe board again to check adjustment;readjust if
necessary.
• Tighten socket head bolts
