A. SETTING UP
Place Superjaws on the ground, upside down. Fit the two front legs
in the correct orientation, as in Fig. 1, using the two large bolts,
washers and nuts. Tighten very firmly. Use the remaining fasteners
to fit the two leg spreaders exactly as shown. (Fig 2)
Insert the angled foot into the rear leg in the orientation shown in
Fig 1a. Fold all three legs outward as far as they will go shown. Pull
out the two front leg spreaders and place the protruding stub on one
s p r e a d e r into the end of the other. Pull up until they are in line. (Fig 3)
Push the joiner across until it hits the stop. (Fig 4)
Unfold the rear cross bar assembly and place the end of the tube in
the socket. Pull up to lock. (Fig 5)
WARNING: Keep hands clear of hinge.
Unfold the foot pedal until it "clicks" home (Fig 6)
Superjaws is packed with the sliding jaw in the reverse position. For
normal operating remove the jaw, rotate it and replace it in its track.
Folding is basically the reverse procedure. Ensure that the lock tab
is in the locked position to prevent the jaw from sliding when folded.
Note that the foot pedal is unlocked by pulling down on the lock bar
trigger before folding. (Fig 7)
B. OPERATING AS A VICE
Clamping
Place workpiece against the front jaw and pull the sliding jaw up to
the workpiece. (Fig 8)
Push down the foot pedal until sufficient clamping force has been
applied then pull out the lock-release plate.
For extra force, you may stand on the foot pedal (max. 100kg /
220lb) but do not jump on it, as this can damage the unit. (Fig 9)
Releasing Clamped Objects
Place your foot into the foot pedal stirrup and apply light pressure.
(Fig 10)
Use either your hand or your knee to push in the lock-release plate.
If you have clamped the object very tightly, you may have to strike
the plate to release.
WARNING: It is possible to unlock the jaws by pushing in
the lock-release plate without applying pressure to the foot
pedal. If doing so, ensure your leg is well clear of the foot
pedal's arc of travel! (Fig 10)
Clamping on one side of the jaw
On occasions, large or awkward workpieces can only be clamped
on one side of the jaws. Always fit a spacer (the same thickness as
your workpiece) to the other side of the jaws, to prevent the moving
jaw from skewing. (Fig 11)
C. RECOMMENDED OPERAT I O N
Before use ensure your Superjaws is correctly assembled with
the legs fully locked.
When working along the line of the jaws, place your foot on the
foot-plate to prevent Superjaws from moving. (Fig 12)
To stabilise Superjaws when working from behind stand on the
crossbar. (Fig 13)
Stand on the front crossbar to stabilise Superjaws when working
close to the jaws. (Fig 14)
D. CLAMPING LARGE OBJECTS (400-900mm /
1 6 " - 35")
To clamp workpieces greater than 400mm (16"), reverse the sliding
jaw. Make sure the lock-release plate is fully in, and the pedal is
fully up. The sliding jaw can then be slid off, reversed, and returned
to the main body. (Fig 15 & 16)
WARNING: Whenever clamping objects with the sliding jaw
reversed, ensure the workpiece sits down onto the sliding jaw,
and is parallel to it. (Fig 17)
Avoid clamping workpieces at the top of the jaws (with a gap
between the workpiece and the sliding jaw) as excessive pedal
pressure could damage the unit. (Fig 17)
Note that for workpieces in the range of 400-485 (16"-19"), a
packing piece as shown is required. (Fig 18)
When clamping large or heavy materials, provide outboard support
(such as a Multi-Stand) to prevent Superjaws from tipping over. (Fig
19)
E. CLAMPING SHEET MATERIALS ON EDGE
It is possible to clamp sheet materials on edge. Use a spacer,
minimum thickness 50mm (2"), to ensure sheet material clears the
legs and foot pedal. Additional, use a small offcut or scrap of sheet
material, to ensure the jaw does not skew when clamping pressure
is applied. (Fig 20)
F. USING A PRESS
When the lock-release plate is fully in, (Fig 21), Superjaws can be
used as a press. With each full stroke of the foot pedal, the rear jaw
will advance about 25mm (1"). You may need to retard the moving
jaw by hand after each foot pedal stroke, to prevent it sliding
backwards on the pedal up-stroke. (Fig 22)
G. USING AS AN ANVIL
The front jaw is sufficiently robust to be used as an anvil for strip
metal work. (Fig 23) For thicker materials we recommend the use
of optional accessory Engineer's Jaws. (Fig 24)
WARNING: Do not use the rear jaw as an anvil. You could
damage it.
ADDITIONAL HINTS AND TIPS
Ripping a Plank
When ripping a plank, stop your cut before reaching the jaws.
Remove the workpiece and re-clamp with sufficient amount of the
cut beyond the jaws, so that you can drop in your saw to
recommence your cut. Before clamping, insert a spacer slightly
thicker than your saw cut, at the jaw area as shown, to keep the cut
open. (Fig 25)
Clamping Plastic Pipe
When clamping plastic pipe, use the optional accessory Engineers
Jaws and wrap a strip of sandpaper around the pipe as shown. (Fig
26)
Clamping Square Tubing
It is easier to hacksaw square tubing or similar on the diagonal. Use
the V-grooves in the urethane jaws to securely hold your material.
