7. Maintenance
Before you start any maintenance activities, always take following precautions:
•
Stop the engine and let the engine cool down.
•
Remove the starter plug cap.
•
If the machine is equipped with an electrical start system, remove the key from the contact and disconnect the battery.
The GTS1000MZ consists out of parts with a weight over 20kg. Never lift these parts alone. Ask someone to help you lifting
these parts.
• Rotor housing +/- 20kg
• Engine +/- 20kg
7.1. Cleaning
Do not clean the machine with high pressure water.
7.2. Verification of the emergency stop button
Start the machine as described earlier. Do not put any material in the input (hopper). Push on the emergency button. The machine should stop.
Release the emergency button as described in chapter 6.5. It is now possible to start the machine again. Execute this check before each use.
7.3. Replacing and adjusting the belts
The belts only need to be replaced when they are worn or damaged. Inspect the belts at least 2 times a year.
Unscrew the bolts of the cover of the belt housing (Fig 16.1).
Remove the cover from the belt housing (Fig 16.2). Un-
screw the bolts fixed horizontally to the engine. (Fig. 16.3).
Loosen slightly the bolts that fix the engine on the chas-
sis (Fig 16.4). Move the engine block in the direction of
the rotor. Now the old belts can be removed and the new
ones can be fitted.
Note that once the belts are removed, it is easy to check
the distance between blades and counterblade, because
the rotor can turn freely.
Tension the belts by moving the engine block away from
the rotor and, once the correct belt tension is found,
block the engine position by screwing tight the 4 bolts to
the chassis.
Once you have got the right tension, check that the pulleys are aligned. You can check this by holding a bar against the pulleys (Fig
16.5). You have reached the right tension when the belt can be pulled down ± 6cm / 2.5 inches (Fig 16.6).
When new belts are fitted the distance between pulley spindles should be +/- 730 mm. Check again after tensioning the belts that the
pulleys are aligned. Check that all bolts are tightened properly. Put the cover for the belt housing back in place and mount the hopper
and output chute.
After changing the belts, let the machine run for 5 minutes without load. While running without load, check the machine for loose bolts,
unusual noises or vibrations. Now the machine is ready for use.
7.4. Greasing the bearinghousing
There are 2 grease nipples on the machine, on both sides of the rotorhouse,
on the bearinghousings (Fig. 17.1 and
nipple and fill the bearinghousing with universal grease.
REMARK: if you have problems reaching the grease nipple on the side of the
belt cover, just loosen the bolt that holds the belt cover attached to the rotor
housing. Now you can pull a little on the belt cover and now you should be able
to fit the grease pump over the nipple. Don't forget to put the bolt back!
Grease the bearing housings at least once a year, using universal grease.
