Maintenance lubrication
Before proceeding with maintenance work, shut down the engine, remove the key and
wait for all moving parts to stop.
There is a grease fitting on the winch, which enables greasing of the upper pulley and
guide. The second grease fitting is on the housing of the lower pulley. Greasing is required
every 60 hours of operation. The PTO shaft needs to be lubricated according to
instructions of the manufacturer.
Non-frequent greasing can cause wear of slide elements and consequentially a defect,
which is not subject to warranty terms!
Drive chain must be lubricated every 200 hours of operation. Lubricate it with spray for
lubrication of chains or special grease, which does not melt at high temperatures,
because the grease can come into contact with friction coating of the clutch.
First, remove the cardan shaft protection, which must be fitted back
after finishing lubrication. Clean the chain before lubrication.
Do not
lubricate the part, where the grease can reach clutch with application.
If grease comes into contact with friction coating of the clutch due do improper and
excessive lubrication, this would mean a drastic reduction in pulling force and
consequentially it would be required to replace the blades of the clutch, which cannot be
a subject of this warranty!
All other bearings on the winch are of closed type, therefore greasing is not necessary.
CONTROL OF HYDRAULIC OIL
Oil level in the tank needs to be controlled occasionally.
Oil level in the tank is 3 liters.
Hydraulic system uses oil for hydraulic systems ISO 32. First oil change must be done after
100 hours of operation. Each next change must be done after 1000 hours of operation or
at least once a year. Oil temperature must be checked during operation. If it exceeds 70
°C, the cardan must be stopped and determine the cause of overheating. If you do not
have a thermometer present, you can determine the oil temperature by touching the
hydraulic line. This must be done only with the engine switched off or else the hydraulic
system can malfunction.
Oil level is controlled with stick on the tank cover (fig. 13).Here you also fill in oil.
With any work on the hydraulic system, pressure in the system must be released. Do this
by pressing the left button on the control console (pos. 1, fig. 8) several times, until the
pressure drops to 0 bar (pos. 1, fig. 14).
Remove the triangular protection on the winch pillar and cardan protection beforehand.
Release the oil from the tank (fig. 13) on the tube, which goes from the pump to the tank.
There is a filter on the bottom of the tank, which must be replace with every oil change.
High-
pressure filter (pos. 2, fig. 14) must also be cleaned.
