WORKING AT EXTREME CONDITIONS
Recommended working temperature range for
trailer is –30°C up to +40°C.
Note
that
working
at
low
temperatures
accelerates hydraulic gaskets wearing and
increases hydraulic hoses exposure to damages
and steel constructions exposure to brittle
fracture. Before start working at cold conditions
let the oil circulate freely through system a few
minutes.
Slowly drive every action through several times
so that gaskets come pliable before they
receive full pressure.
At exceptionally warm conditions beware of
hydraulic oils excessive heating. Too high oil
temperature (higher +80°C) degrades oil and
damages gaskets.
4 MAINTENANCE INSTRUCTIONS
4.1.
SAFETY
READ THE MAINTENANCE INSTRUCTIONS BEFORE
SERVICE OR MAINTENANCE WORKS. DO NOT ATTEMPT
TO PERFORM SUCH MAINTENANCE WORKS WHICH YOU
DO NOT FULLY UNDERSTAND
Repair all safety endangering defects
immediately.
Check that the trailer is on a level and
stable ground.
Use vehicles parking brake during
maintaining the trailer. Make sure that
nobody can unnecessarily have access
to trailers or vehicles controls.
Never attempt to do maintenance works
on the hydraulic system before you are
sure there is no pressure.
Do not tighten or repair a leaking
hydraulic couplings while the system is
pressurized.
Never attempt to localize a leakage from
hoses or connections by feeling with
hand. The high pressure oil jet can
penetrate skin and cause serious burns
and damages. High pressure oil is also
highly flammable.
Do not work under such device that is
sustained only by hydraulics. During
maintenance use supports.
Avoid getting oil into eyes. Use safety
goggles and gloves.
