Maintenance and service

Maintenance and service

The machine must always be secured before any
type of service or maintenance work is
commenced.

Never stand near hydraulic hoses under pressure.
Drain the system’s accumulators before servicing
the hydraulic system.

9.1

Safety when servicing

Always shut down the tractor and take out the
ignition key when carrying out work on the
machine.

The machine must always be secured before any
type of service or maintenance work is
commenced.

Never stand near hydraulic hoses under pressure.
Recover all spilled oil after servicing the
hydraulics system.

Note that poor welding may result in serious
personal injury or fatality. If you are unsure,
contact a professional welding technician for
instructions.

Exercise extreme caution when undertaking any
kind of work with the machine’s hydraulic
system. Wipe with clean paper or cloths. Place
parts on a clean surface (not directly on the work
bench) Rinse before assembly, for example with
a decreasing agent.

Never rinse the bearings with a high pressure
water supply! It is important to grease the
bearings after washing in order to remove any
water that has remained behind.

Never clean bearings directly with a high-
pressure water jet. Clean electrical components
by blowing them with air or by wiping them with
a slightly dampened cloth.

To maintain the machine’s high level of quality
and operational safety, use only Väderstad
genuine spare parts. The warranty and any claims
under it will become void if parts other than
genuine parts are used.

Figure 9.1

1. Lubricate the machine according to the intervals

specified in the lubrication schedule, and always
before and after winter storage and after high-pressure
water cleaning.

2. Before operation, ensure that all nuts and bolts have

been tightened (does not apply to bolts in flexible
joints).

3. During the season, check periodically that the nuts

and bolts have not worked loose and inspect joints
and hydraulic ram mountings for wear.

9.2

Securing the implement for service

When work is to be performed on the
implements, the machine must always be parked
on a stable and level surface.

When working on the hydraulic system, the
wings must be folded down and the implement
lowered to the ground.

If the hydraulic system includes accumulators,
these must be drained of oil before carrying out
the service or repair work.
