PLACING SAW AND EXTENSION TABLE ON MOBILE BASE

RISK OF INJURY FROM

LIFTING. Serious injury can result from attempting to lift too heavy an object. The machine can weigh more than 550 pounds and is too heavy to be lifted by one person. Obtain assistance from others before lifting.

PINCH HAZARD. Be sure not to place toes or fingers underneath the base of the Unisaw while moving. Lift the saw from underneath the table, before saw is assembled, or from underneath the wings and extension table after assembly.

Carefully lift saw and extension table onto mobile base. Make sure extension legs (EE) Fig. 7 rest on angle brackets (I) as shown.

Saw base frame

INTRODUCTION

This mobile base features welded, heavy-gauge steel supports with a bolt-on foot lever, a single swivel caster, and two sturdy wheels. Rubber feet positioned opposite the fixed wheels assure stable contact when the base is lowered into the stationary position. The convenient foot lever raises and lowers the base for ease in moving and positioning the machine, and allows the machine to be moved aside for cleaning purposes.

ASSEMBLY

NOTE: Do not place Unisaw on the mobile base until the base is fully assembled.

NOTE: The saw frame (S) Fig. 1 comes fully assembled. User must attach fixed wheels, angle brackets, rubber feet, swivel caster, foot pedal assembly and J bolt anchors.

resting properly on the base while moving the base.

1.Place 1/4-20 hex nut (S) Fig. 7 on J-bolt

(P)and screw it on until it bottoms out on threads.

2.Make sure J bolt (P) Fig. 7 is around leveling screw (GG) on extension leg (EE) as shown in Fig. 7.

3.Insert J bolt (P) Fig. 1 and Fig. 7 through hole

(FF)Fig. 3 in angle bracket (I).

4.Adjust hex nut (S) until it touches the angle bracket (I).

5.Place a 1/4" flat washer (Q) Fig. 7 on J bolt

(P)and fasten it to angle bracket (I) using a 1/4-20 Nylon lock nut (R). Tighten nut using 7/16" wrench.

6.Repeat for J bolt (P) on the other angle bracket (I).

OPERATING MOBILE BASE

NOTE: Before operating the base, apply grease to the cams (HH) Fig. 8 and where they meet the foot pedal bracket (AA).

When the foot pedal (II) is pushed down as shown in Figure 9, the base is mobile.

To reduce the risk of injury, do not operate the saw when the base is mobile

ASSEMBLING FIXED WHEELS IN SAW BASE END

1.

Place the sleeve (M) Fig. 2 into hole in fixed

 

wheel (K) and place wheel inside the saw

 

base frame as shown.

2.

Slide a 2" (50.8 mm) shoulder screw (L)

 

Fig. 2 through bottom hole (U) at saw base

 

frame end and then through the hole (V) in

 

the wheel (K) and out the bottom hole in the

 

other side of saw base frame bracket.

3.

Place a 5/16 flat washer (N) Fig. 2 on the

 

threads of the shoulder screw and tighten

 

a 5/16-18 Nylon lock nut (O) onto the end

(when the foot pedal (II) is pushed down as shown in Fig. 9).

When the foot pedal (II) is raised (as shown in Figure 10), the base is lowered down to the floor so it does not move. If the saw is not level in this position, you can adjust the two extension table legs (EE) Fig. 7 on your Unisaw using the leveling screw (GG).

To reduce the risk of injury, when lifting on foot pedal (II) Fig. 9 to lower the saw down and make it stationary, be careful as the pedal swings back with force. Stay clear of the motion of this pedal.

of the shoulder screw (L). To tighten, hold

shoulder screw (L) with a 3/16 hex wrench

and tighten Nylon lock nut with 1/2" socket

wrench.

4. Repeat these steps for other wheel.

ASSEMBLING ANGLE BRACKETS AND RUBBER FEET

1.Line up two holes (W) Fig. 3 in angle bracket

(I)with two holes (X) in saw frame extension end. Insert two 5/16-18 x 3/4” (19 mm) hex head serrated flange bolts (J) through holes

(W)in the bracket and into the tapped holes

(X)of the saw frame extension end. Tighten these down with 1/2" socket wrench.

2.Insert rubber foot (A) Fig. 4 up through hole in angle bracket (I) as shown.

3.Attach 1/2-13 jam nut (B) Fig. 4 to post of rubber foot (A) and tighten down with 3/4" wrench.

4.Repeat all steps for other angle bracket and rubber foot.

ASSEMBLING SWIVEL CASTER TO PEDAL ASSEMBLY

To reduce the risk of injury, make sure that your feet are clear of the base before lowering the unit.
