8. Connection –disconnection
The machine is constructed for connection to tractor hydraulic lift or loader, connected
to tractor hydraulic lift.
8.1 Connection on a tractor
To tractor hydraulic lift
Move the tractor to the three –point connection of the pliers for timber, until the bolts
of the three –point connection and the bolt holes on the lower liftable crossbars on
a tractor do not match.
Be aware of the thing, that between the tractor and pliers for timber are not located
any persons.
Insert the bolts in the holes and secure them with tractor pin.
The tractor must be switched off, when the driver switches control lever on hydraulics.
Set up upper lever 1 to the desired length and fasten and secure him on the upper
part of the three –point connection (Figure 1). Connect hydraulic lines on a tractor.
Move support leg 3 in transport position (figure 2).

8
To loader
The procedure is identical as for any other tool for loader, only here you have to connect
tongs for logs. Between the tractor and tongs for logs no persons, animals or object are
allowed. The tractor must be shut down, when the driver connects the hydraulics.
Connect hydraulic line to tongs for logs according to hydraulic version of tongs. Move
support leg 2 in transport position (figure 2).
Pliers for timber after the finished work always put down in a closed condition.
8.2. Disconnection of a tractor
From tractor hydraulic lift
Move support leg 3 in support position (figure 1). Pliers for timber before disconnecting
them from the tractor, always put down on a flat and solid ground in the closed
condition. First check, whether the pliers are secured against the movement with bolt 2
(Figure 2). Disconnect the hydraulic hoses, place protection on the quick thimbles and
insert them into the place on connection. In the case of the steering console, insert her on
a supposed place on a connection. Upper control lever loosen and disconnect. Lower
tractor arms disconnect.
From loader
Move support leg 3 in support position (figure 1). Put tongs for logs on flat, solid ground,
when they are closed. Check beforehand that the tongs are secured against movement
with bolt 2 (figure 1).
Disconnect hydraulic lines, set protections for quick clamps and put them on the storage
place on the connection. Disconnect from the loader.

9. Handling
Pliers for wood are handled through steering device of a tractor or with solenoid valve.
ATTENTION!
By using the pliers handle hydraulic cylinders and hydraulic rotator without sudden
movements and with
appropriate low flows to 40l/min. Do not overload the pliers above the allowed
weight.
Carrying the trunks always perform as the instruction book defines.
Vital parts always check before use, so that there are no possible injuries.
By injuries that would arise because of noncompliance of the machines instruction
book, warranty terms do not valid and the manufacturer eliminates defect at the
expense of the buyer.
9.1. Transport
When the pliers for wood are operating, unauthorized persons must not be located in the
range of a working machine. When driving on public road it is necessary to install a
warning plate on the pliers and the lights should be switched on, we must also secure the
swinging with the bolt 1 (Figure 4).

9.2 Angular setting between tractor arms and controlling pole
Pliers are designed to draw trunks and occasionally loading. According to the purpose of
use, it is necessary to adjust the height of fasten the tractor arms on pliers as well as upper
steering lever of the three –point connection.
• When you want to use pliers to draw trunks, set the tractor arms 1 and upper
steering pole 2 parallel, as much as possible (Figure 5).
• But if you want to load with pliers, then the angle between tractor arms 1 and
upper steering pole 2 should be as bigger as it can (Figure 6).
