SAFETY RULES
W oodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are cert ain
hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possi bility of personal injury . However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce
your potential for injury . But even the best guard won t make up for poor judgment, carelessness or inattention. Always use common

UNPACKING A ND CLEANING
Carefully unp ack the band saw, stand, mobile base, and 12 cap acity rip fence from the shipping cont ainers. Remove
the protective coating from the machined surfaces of the band saw. This coating may be removed with a sof t cloth moist ened with kerosene ( D O NOT use acetone, gasoline or lacquer thinner for this purpose). Af ter cleaning, cover all unpainted surfaces with a good quality p aste wax. Fig. 2, illustrates the component s of the mobile base. Fig. 3, illustrates
the components of the rip fence.

ASSEMBLING THE MOBILE BASE
The mobile base is constructed of heavy gage steel with
welded joint s and features a bolt-on foot lever assembly,
single swivel caster , and rigid wheels. T wo adjust able
foot p ads opposite the rigid wheels assure st able fourcorner cont act when the base is lowered. A convenient
foot-operated control lever raises and lowers the base for
easy movement for cleaning and repositioning.
3. Fig. 6, illustrates the caster assembly (F) and foot
lever assembly (A) fastened to the mobile base (B).
4. W ith the foot lever (A) Fig. 7, in the raised position
as shown, the mobile base should be level with the floor
surface and the two rubber feet, one of which is shown
at (L), should cont act the floor surface. To adjust the rub ber feet, tighten and loosen the hex nut, which is shown
at (M) and the nut which is located directly above the
rubber feet.
5. IMPORTANT:WHENPLACING THE MACHINE ON
THE MOBILE BASE, MAKE CERTAIN FOOT LEVER
(A) F I G . 7, IS IN THE RAISED POSITION A S SHOWN
TO AVOID MOVEMENT OF THE MOBILE BASE.
2. Assemble caster assembly (F) Fig. 5, to mobile base
bracket (G) using the four inch-long screw (H) through
two holes (J) in mobile base bracket (G) and two holes in
caster assembly (F). Fasten in place using locknut (K).
1. Assemble foot lever assembly (A) Fig. 4, to the out side of mobile base (B) with two 1-1/2 inch-long hex head
screws (C), four flat washers (D), and two hex nut s (E).

RAISING A N D LOWERING THE MOBILE BASE
1. To raise the mobile base (B) Fig. 8, and allow movement to a new location, push foot lever (A)
downward until the foot lever locks into position.
2. To lower the mobile base (B) Fig. 8, so it is supported by the floor surface, flip foot lever (A) upward.

ASSEMBLING THE BAND SAW
The st and is shipped top down inside the shipping cont ainer with the motor mounted to the inside top
of the st and. The on/off switch is wired to the end of the power cord.
The motor must be removed from the inside top of the st and and reassembled to the horizont al mount ing bars inside the st and as follows:
1. Remove the stand (A) Fig. 9, from the shipping con -
tainer being careful not to crimp the switch cord which
extends through the top of the st and. NOTE: Set the
st and on several blocks of wood to raise the st and of f the
floor surface.
2. Remove panel (B) Fig. 9, from st and (A) by removing
two screws (C) and loosening two screws (D). Remove
