Engaging :
1. Push the rope release lever towards the anchor point.
2. Press and maintain pressure on the rope release
safety catch, allowing the release lever to slowly tra-
vel back to its original position. Release the safety
catch. The release lever locks in position under the
effect of its spring.

Releasing :
Turn the rope release safety catch (5) and push the rope
release lever (4) towards the anchor pin until it locks into
position when raised slightly at its limit. Release the
safety catch.

ANCHORING

Failure to anchor the TIRFOR
runs the risk of a serious accident. The user must
always ensure before operation that the anchor
point(s) for the machine and wire-rope are of suffi-
cient strength to hold the load.
It is recommended that TIRFOR
anchored to a fixed point or to the load using an appropria-
te capacity sling. It is forbidden to use the machine's
wire rope as a sling by passing it around the load and hoo-
king it back onto itself (Fig.10-1 : incorrect anchoring arran-
gement; Fig.10-2 : correct anchoring arrangement ).
The anchoring arrangement of models TU-8 and TU-16
is a hook fitted with a safety catch (Figs. 11 and 12 ). In
all cases when anchoring the machine the safety catch
of the anchor hook should be correctly closed, in its
position at the tip of the hook (Fig.12). This advice for
the machine anchor hook also applies to the hook fitted
to the wire rope.
TIRFOR ® machines TU-32 and T-500D are anchored by
means of a removable anchor pin, fitted across the two
ends of the side cases (Fig. 13 and 14) and locked in
position by a spring clip (Figs. 15 and 16).
Optional hooks are available to fit the anchor point of
models T-500D and TU-32.
To anchor using the anchor pin, follow the procedure
below:
1. Open the spring clip of the anchor pin.
2. Remove the spring clip from the anchor pin.
3. Slide the anchor pin out of the side cases (Fig.14).

4. Fit the anchoring arrangement, such as a sling, bet-
ween the side cases.
5. Refit the anchor pin through the side cases and
anchoring arrangement, such as the eyes of a sling.
6. Refit the spring clip to the anchor pin.
7. Close the spring clip, ensuring that it fits correctly
over the end of the anchor pin and cannot fall out.
Warning : It is essential for the safe operation of
the machine to ensure that, before loading the machine,
the anchor points, hooks or pins, are correctly secured,
(with the safety catch correctly located on the hook - Fig.
12).

6. OPERATION

TIRFOR ® machines are very easy to use. Place the
telescopic operating handle on either the forward or
reverse operating lever, lock it into position by twisting,
and move the operating handle to and fro. The operating
arc is variable for ease of operation.
When operation stops, both jaws automatically grip the
wire rope and hold the load which is spread equally bet-
ween the jaws.
The to-and-fro operation of the forward or reverse lever
gives continuous movement of the load.

7. RELEASING THE WIRE ROPE AND STORAGE

It is essential to take the load off the machine befo-
re attempting to release the jaws. To do this, operate
the reverse operating lever until there is no tension in
the wire rope.
Remove the telescopic operating handle and return it to
the closed position.
Release the machine and follow the instructions for ins-
talling the wire rope in the reverse order. Re-engage the
jaws of the machine before putting it into storage.
Store the machine and wire rope in a dry place, away
from the effects of the weather. The wire rope should be
completely removed from the machine and rewound
onto its reeler.
Before reeling the wire rope, it is recommended to ins-
pect it, clean it with a brush and then grease it. (See
section 10).

8. SAFETY DEVICES

8.1. Overload limiting safety devices
All TIRFOR ® machines incorporate a shear pin system.
In case of overload, one or more pins (depending on the
model), fitted to the forward operating lever, shear and
prevent further forward or lifting operations. Reverse
operation is still possible to enable the load to be lowe-
