ADJUSTING THE DRIVE PULLEYS
The drive pulleys on the spindle shaft and the motor
shaft may loosen during shipment. It is crucial that these pulleys are the
same height on their respective shafts. Failure to square these pulleys could
result in premature belt wear or damage to the motor and spindle bearings
or both.
1. Lay a straightedge across the tops of the three
pulleys. If properly adjusted, they should all
touch the straightedge.
2. Adjust the pulleys if necessary.
3. To adjust the motor pulley, loosen the setscrew
that attaches the pulley to the shaft using a hex
wrench.
4. Move the pulley up or down until it is in line
with the straightedge. Tighten the setscrew.
5. If the pulley is still not in alignment, using an
adjustable wrench, loosen the four (4) bolts
holding the motor onto the column bracket.
6. Slide the motor slightly upward and retighten the bolts. Make the final adjust-
ments by repeating steps 1 through 4.
7. To adjust the spindle pulley, loosen the setscrew with a hex wrench and slightly
move the pulley upward or downward until it is in line with the straightedge.
Tighten the setscrew.
8. When finished, recheck the alignment of all three pulleys with the straightedge
ensuring they are all the same. Make any final adjustments necessary.
INSTALLING THE DRIVE BELTS
1. Remove the (2) two V-belts from the loose parts bag.
2. Open the belt guard. Select the proper belt orientation for the correct speed for
the drilling operation from the speed chart located on the inside top of the belt
guard.
3. The longer of the two V-belts always goes from the spindle pulley to the center
idler pulley.
4. The shorter of the two V-belts always goes from the idler pulley to the motor
pulley. This belt is always installed first.
5. Loosen the tension lock knob (located
on the right side of the head as you
face toward the rear) in a counter-
clockwise direction.
6. Moving the motor toward the front of
the drill press, slide the shorter of the
V-belts over the idler pulley and the
motor pulley.
7. Slide the longer of the V-belts over the
idler pulley and the spindle pulley.
8. Move the motor towards the rear of
the drill press and tighten belt tension
lock knob.
9. The V-belts should deflect about 1/2"
thumb pressure at the center for proper
tension.
10.Should the drive belts slip during drilling operations, re-tension the drive belts.
Over-tensioning a drive belt may cause the motor to not
start or may cause damage to the motor bearings or the spindle bearings. If
you suspect there may be bearing damage, contact Alltrade Customer
Service at 1-800-590-3723. Do not attempt to make repairs yourself.
INSTALLING THE FEED HANDLES
1. Locate the (3) three feed handles in the loose
parts box.
2. Screw the feed handles into the threaded holes in
the pinion shaft located on the head assembly
just above the drill chuck.
3. Tighten the feed handles.
