Maintenance And Lubrication - Grillo DUMPER 406 Manual De Instrucciones

CAUTION!
- Disconnect the plug before performing any cleaning, maintenance or repair operation. Always wear suitable
clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always remember to use suitable
fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without safety locks or supports,
never leave it unguarded in places where inexperienced people and children could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
Note: all checks have to be carried out with the machine in horizontal position.
ENGINE OIL
Follow the instructions on lubrication intervals in the relative manual. In general users are advised to check the oil level
every 4 working hours and replace it every 100 hours (fig. 9, n. 1).
GEARBOX OIL
Check the level every 50 working hours and add 85W90 oil if necessary. Replace the oil once a year (quantity 1,350 kg)
by loosening the screw (fig. 8).
ENGINE AIR FILTER
Check the filter every 8 working hours. For engines equipped with a dry air filter replace the cartridge when it is too
clogged (do not use compressed air to clean it). For engines equipped with oil-bath filter, add or replace oil. Use the
same oil as for the engine.
TRACK ROLLERS
- Frequently grease the track roller pins (fig. 6)
- Frequently check the track roller tension
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 tracked carrier 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, when releasing the lever (fig. 7, pos. B) the
parking brake is automatically engaged. Although the truck has rubber tracks, remember to take care in difficult
environmental conditions (ice, heavy rain or snow) or on terrains which might make the vehicle unstable.
1) TRACK TENSION
1) When the machine is lifted off the ground, the rubber tracks must sag by 10-15 mm as shown in the diagram.
2) When the track becomes slack, it must be adjusted to prevent the machine via the adjusting screw (fig. 6).
2) PRECAUTIONS WHEN DRIVING
1- Avoid jerky operations when the crawler truck is in motion.
2- Keep the rubber crawler track away from sharp edges of concrete etc.
3- Cracks on the outside surface of the rubber track (in contact with the ground) are very often due to contact with
gravel, sharp stones and sharp materials such as sheet metal, nails and glass.
3) AVOID SUDDEN CHANGES IN DIRECTION
Sharp turns on concrete surfaces or excessive accelerations which generate high friction coefficients
must be avoided since they might cause cuts in the rubber.
4) AVOID CONTAMINATION WITH OIL
Fuels and hydraulic fluids must never come into contact with the rubber crawler track. If this should
occur, clean immediately.
