6.6.4 Stretching of the drive chains
After the first operation hours you may possibly experience some extent of release of the drive chain
that will then need to be restretched. Under normal continuing operating conditions the drive chain
should be stretched every 60 operating hours. To perform stretching of the drive chain (fig. 8):
• Remove the safety guard (Pos.1), unscrew the fixation screw (Pos. 2 ) and finally loosen the 4 ad-
justment screws (Pos. 3).
• Loosen the nut (Pos. 6) of the tension screw (Pos. 4) and tighten the tension screw on nut (Pos. 5)
• Keep tightening nut (Pos. 5) until the drive chain (Pos. 7) is duly stretched
• Under a hand pressure, the duly stretched chain must be still capable of minimally moving
• Turn the PTO driveline (Pos. 8) and make sure that this is effortlessly done
• Check the pump drive chain (Pos. 9) and perform new stretching if required. To do so, release the
screw (10) and tighten with nut (11) making sure to avoid excessive tensioning of the chain
6.7 Lubrication
Make sure that the motor is switched off, pull out the tractor keys and wait for
all moving parts to be secured before performing any maintenance/repair work
on the machine.
4 lubrication nipples are available on the winch to respectively perform lubrication of both the upper
and lower snatchblocks and of the rope fairlead. Perform lubrication of the nipple (13) of the pre-bra-
king arrangement (12, Fig. 8).
Make sure to perform lubrication every 15 - 20 operation hours.
CAUTION: improper lubrication may cause dangerous contamination of the sliding parts. In
this case the manufacturer will not be liable for any resulting damage or injury!

Lubricate the driving chain after every 40 operation hours.
To lubricate the driving chain use grease suitable for high temperature (it should not melt as common low-price lithium
grease) in order to prevent grease contamination of the sliding clutch surfaces. Strictly use special spray lubricant for link
chains. Provide regular maintenance of the drive chain by removing any eventual residual dirt before greasing it.
BE AWARE: Do not grease the clutch lining because this may lead to a
significant reduction of the line pull and in this case you may be forced
to replace the clutch plates!
All other bearings are self-lubricating ones that require no further lubrication or maintenance.
Provide PTO shaft lubrication in accordance with the instructions of the manufacturer (Fig. 10).
6.8 Checking the hydraulic oil
Perform periodical oil temp checks during operation. Should the
oil temp exceed 70°C, stop the motor, search for the possible cau-
ses and fix the overheating problem before continuing to work.
BEWARE: longterm overheating may permanently damage your
winch hydraulics.
