OPERATING INSTRUCTIONS

NOTE: Before using the tool, read the

instruction book carefully.

SET-UP INSTRUCTIONS

1. Put the JAWHORSE

upside down on the ground,

loosen the rear leg locking knob (5) and slide the

rear leg from its storage position. Pivot the leg to

position and slide it all the way upward then lift and

slide it fully into its housing at the rear. Tighten the

knob. (See Fig. A-C)

2. Raise the foot pedal (9) until it “clicks” into position.

(See Fig. D-E)

3. Rotate the front legs (10) all the way forward until

they “click” into position. The front leg locking latch

(15) will be open automatically. (See Fig. E)

4. Turn the JAWHORSE

upright and recheck that all

legs are locked ﬁrmly in position.

FOLDING INSTRUCTIONS

Folding is the reverse procedure of above. (See Fig. F-K)

1. Ensure that the lock / release switch is in the

“unlock position”. (See Fig. F)

2. Turn the unit upside down. Slide the front leg latch

and fold the front legs into position. (See Fig. G)

3. Draw the foot pedal locking latch and place the foot

pedal in folding position. (See Fig. H)

4. Loosen the rear locking knob. Slide the rear leg from

housing and back into storage position. Make sure

the rear leg is engaged fully into storage position

and the rear leg locking knob is tightened ﬁrmly.

5. You can carry the rear leg as a carry handle when

the JAWHORSE

is fully folded in its position. (See

Fig. I)

6. You can also slide the rear leg to use as a handle.

With the roller on the front, transporting the

JAWHORSE

is easy and fast. Note that the roller is

not designed to withstand rigorous transport, such

as bouncing down stairways or traversing rough

terrain. (See Fig. J, K)

CLAMPING

1. Place the workpiece against the ﬁxed jaw (14) and

slide the moving jaw (1) forward until it touches the

workpiece.

The foot pedal can be pressed repeatedly to make

the jaw move forward.

2. Slide the lock / release switch down to the “lock”

position. (See Fig. L)

3. Apply downward pressure on the foot pedal until

enough clamping force is applied. (See Fig. M)

WARNING: Maximum allowable force on the

foot pedal is 220 lbs (maximum 100 kg). Do

not stand or jump on the unit, as you can cause

injury or damage the unit.

RELEASING

1. Slide the lock / release switch up to the “release”

position. (See Fig. F)

2. Push on the foot pedal, allow it to return up and

release the workpiece. (See Fig. M)

If you have clamped the object very tightly, you must

exert similar pressure on the foot pedal before it will

release.

WARNING: Ensure you are supporting the

workpiece to avoid its falling when the jaw is

released.

3. Slide the moving jaw back and remove your

workpiece. (See Fig. N)

CLAMPING ON ONE SIDE OF THE JAW

Sometimes, large or awkward workpieces can only be

clamped on one side of the jaws. In this case, be sure to

avoid excessive clamping force.

CLAMPING SQUARE PIECES VERTICALLY (See Fig. O)

Sometimes, tubing or other square (steel, aluminum or

other) workpieces need to be clamped vertically on the

center of the jaws. The hole on the base plate under the

jaw accommodates pieces up to 2 3/8 in width.

CLAMPING LARGE OBJECTS [17 1/4˝ (450 mm) TO

37˝ (940 mm)

The move jaw can be reversed to accommodate large

workpieces.

1. Set the lock / release switch to the “release”

position and ensure that the foot pedal is released.

2. Slide the moving jaw (1) fully from its tracks. (See

Fig. N)
