SAFETY PRECAUTIONS

WARNING: AS WITH ALL MACHINERY, THERE ARE CERTAIN HAZARDS
INVOLVED WITH THEIR OPERATION AND USE. EXERCISING RESPECT AND
CAUTION WILL CONSIDERABLY LESSEN THE RISK OF PERSONAL INJURY.
HOWEVER, IF NORMAL SAFETY PRECAUTIONS ARE OVERLOOKED OR
IGNORED, PERSONAL INJURY TO THE OPERATOR OR DAMAGE TO
PROPERTY, MAY RESULT.

1. Understand the equipment. Learn the pullers' applications and limitations
as well as the specific potential hazards peculiar to it.

2. Always inspect the puller before
use. Ensure that all parts are in good
condition and operating smoothly,
and that no cracks or distortion is
apparent and the rope is not
corroded frayed or damaged in
any way. If in doubt do not use.

3. Do Not use the Puller for lifting
purposes.

4. Do Not exceed the pullers'
capacity.

5. Do Not use handle extensions.

6. Ensure that all personnel stand well clear of the load, and are not between
the load and the Puller.

7. When using a car as an anchor point ensure that it is 'in line' with the load,
so that the rope does not pull the car sideways.

8. Do not pass the wire rope around tree trunks or gate posts etc., to be used
as fulcrum points (see fig. 1) The abrasive action will cause severe damage
to the rope.

9. Do not prevent the tool from pivoting to line up with the direction of pull
(See fig.1).

10. It is strongly advised that industrial gloves are worn at all times when using
the puller. Take care not to trap fingers within the moving parts.

11. When pulling or dragging a load, be aware that the load may suddenly
'give', e.g. Pulling a tree stump etc. Take the necessary precautions.

12. Never allow the rope to be unwound completely. Ensure there is at least
ONE complete turn on the drum.

13. Do Not wear loose clothing, which could become entangled with the
moving parts.

OPERATION (REF. FIG. 2)

1. WINCHING IN

Set the Forward/Reverse Latch (A) in the position shown (in solid lines) in fig 2.
This ensures the Pawl (B) is held firmly into contact with the Ratchet Wheel (G)
under pressure of Spring (L).

The load is locked in position by Locking Lever (D) engaging with a tooth of
the ratchet wheel.

Move the Handle (E) so that it is pointing towards the load. Now, pulling the
handle away from the load, winches the load 'in'.

When the pressure on the handle is relieved slightly, at the end of its travel, the
locking lever (D), engages with one of the teeth of the ratchet wheel, thereby
locking the load once more and the cycle is repeated.

2. WINCHING OUT

The Hand Puller has the capability of 'winching out', under control, one ratchet
tooth at a time.

Move the forward/reverse latch to the position shown in dotted lines (fig. 2),
freeing the handle to move in the direction of the anchor. (The load
meanwhile is being held by the locking lever).

As the handle nears the end of its travel, the pawl is forced into contact with
the ratchet wheel by the spring loaded Locking Lever Plunger (C) and
eventually locks into one of the teeth.

Continue to turn the handle, causing the pawl to turn the ratchet wheel
slightly, taking the full load from the locking lever (i.e. effectively, winching 'in').
When you have taken the full load, allow the handle to move back towards
the load. The ratchet wheel will move one tooth, paying out the rope by the
same amount until the locking lever locks into place once more under its'
spring pressure preventing any further movement and the cycle is repeated.

NOTE: It is necessary to move the handle only by a small amount each cycle.

3. PAYING OUT THE WIRE ROPE

In order to pay out the wire rope, first ensure the forward/reverse latch is set to
the position shown in dotted lines, fig. 2, so that the pawl is held off the ratchet
wheel.

Holding the Puller firmly with the handle uppermost, and preferably wearing a
good pair of heavy duty gloves, press the locking lever (D), up, thereby
disengaging the locking lever from the ratchet wheel. It is now possible for an
assistant, also wearing gloves, to pull the wire rope out, or, having anchored
the ropes' hook, walk backwards with the puller to the anchor point, paying
out the rope behind you.

Release the locking lever, and re-set the forward/reverse latch to begin
winching 'in'

4. 2:1 OR DOUBLE CABLE WINCHING

The wire rope is provided with a drop forged safety hook, and a third hook
with a pulley attached, which allows a 2 to 1 configuration. To accomplish this,
the main hook is looped back and hooked over the bolt which secures the
cable guide (K).

The third hook, with pulley, is then attached to the load. The length of pull is
thereby halved, but the load capability is doubled.

5. WINCHING IN CONFINED SPACES

The third hook may also be used to
winch a load which is not directly
in line with the anchor. An
example is shown at fig. 3, where
the wire rope passes over the
pulley of the third hook which is
firmly anchored, and from there to
the load.

MAINTENANCE

WARNING: NEVER RUN YOUR BARE HANDS ALONG THE WIRE ROPE,
ALWAYS WEAR A PAIR OF GOOD QUALITY HEAVY DUTY INDUSTRIAL
GLOVES.

1. Inspect the puller before use to ensure that it is in good condition and not
damaged in any way. If cracks appear in the frame, do not use. In this
event, the tool is past its useful working life. If the frame is distorted, the tool
is considered to be beyond repair and should not be used.

2. Keep the pawl, the ratchet pivots, and the rope, lightly oiled at all times.

3. Inspect the wire rope periodically for corrosion, kinks, broken strands etc. If
corrosion is apparent, clean with a stiff wire brush and lightly oil. A
damaged or badly corroded rope must be replaced.
