5 Maintenance and service
NOTE!
During all work under the drill or where there is a danger of crushing, the drill must be
completely and securely supported. Secure the drill on trestles or stands and lock all lifting
rams with their yellow locking devices. See ”3.21 Locking the lifting rams during service” on
page 66.
Ensure also that the surface supporting the trestles is firm enough to support them. If the hopper
is full, which it ought not to be, the weight of the drill is considerable. A full RD 300 F weighs
around 4 500 kg, an RD 400 F around 6 000 kg and an RD 450 F 7 000 kg, so the supporting trest-
les must therefore be approved for weights greater than 3 000 and 3 500 kg respectively.
The platform can be folded up to allow access for some service operations, see ”3.20 Folding plat-
form, mfg. no. -10 309” on page 66.
5.1 General maintenance
Figure 5.4
A machine is only as good as the service it receives!
Before starting work, check that all nuts and screws are tightened. During the season, check the
tightness of nuts and screws regularly, as well as the wear on linkages and the hydraulic ram
mountings.
NOTE!
The screws holding links should not be tightened so much that movement in the linkage is
restricted.
The hydraulic system does not normally require any maintenance, but check that the hoses and
couplings are undamaged.
NOTE!
Dirt must be kept out of the hydraulic system during any service work. Wipe with clean
paper or a clean rag. Lay the parts on a clean surface (not directly on the work bench). Rinse off
parts with e.g. a degreasing compound before fitting them.
Always grease the piston rods after cleaning them or if the drill is not going to be used for a long
time.
Grease galvanized and chromium plated surfaces before long periods of storage.
To maintain the quality of this seed drill, always use Väderstad original spare
parts.
