the accompanying user manual.
Hydraulic oil recommendations

Painting the lifting gear
The lifting gear is powder-coated black ex-works. If another color is desired, painting must be
performed by the vehicle manufacturer.
IMPORTANT:
Roughen the powder-coated surface before painting.
Mask the black connecting rods before painting.
Carefully remove extra paint and masking material from the connecting rods after painting to
avoid damaging the seals and voiding the warranty.

Once the liftgate has been assembled, installed on the vehicle, adjusted, and has passed the
function test, a qualified specialist must fill out and sign the section of the inspection record
book entitled “Results of test performed by specialist before first operation.”
