Grillo Dumper 406 [11/44] Maintenance and lubrication

FINISHING WORK

Return the throttle lever (4, fig. 1) to the idling position. To stop the engine, push the engine cut-off switch (Fig. 1, ref. 11).

MAINTENANCE AND LUBRICATION

The truck is designed to require very little maintenance. However, in order to keep it at top performance, the fol-

lowing operations are advisable:

- check that all the nuts and bolts are always firmly tightened;

- oil the throttle, clutch and brake cables;

- never use mineral oil on rubber parts as it will damage them;

- always check the oil levels and clean the air filter often;

Use 10W30 (API SE) engine oil in summer and winter. Always consult the engine instruction manual.

AIR FILTER

Check the air filter oil level every 8 working hours or more often in very dusty conditions. Top up with the same

oil as for the engine (see engine handbook). On versions with dry filter, replace the cartridge if clogged (do not

clean with compressed air jets).

GEARBOX OIL

Check the level about every 50 working hours and top up if necessary with MP 85W/90 gearbox oil. Change the

oil once a year (quantity 1.35 kg). To drain the old oil from the gearbox, remove the screw (Fig. 8).

TRACK ROLLERS

Periodically grease the track roller pins, especially if the machine is working on sandy terrain (g. 6).

– Never work at full throttle.

– Remove any leaves or grass which accumulate on the grille around the engine pull-start.

The truck capacity is 400 kg, but users are advised to consider the terrain on which the vehicle is to be used when

deciding the load which can be transported. Remember that since this is a crawler vehicle, it pitches considerably

on humps, curbs and steps. When crossing such obstacles, use low gears and take special care; engage a low

gear and retain it until back on level ground. If the machine is stopped on steep slopes, release lever (1, Fig. 1) thus

blocking the truck automatically (B, Fig. 7). Although the truck has rubber tracks, remember to take care in difcult

environmental conditions (ice, heavy rain or snow) or on terrains which might make the vehicle unstable.
