5.3. Connecting the PTO shaft
Telescopic articulated shaft should hold CE marking, and is mounted onto gritter's PTO splined
extension and tractor's PTO shaft. Bushings of shaft’s extensions should be installed onto splined
journals until lock pin is inserted into hollow. Shaft guards should be protected against getting
rotated by means of a chain.
WARNING!
When changing the tractor, with which the machine operates, control the
length of PTO shaft again (Fig. 7).

Fig. 7. Length of PTO shaft control
Before starting the machine check the length of articulated telescopic shaft as follows:
 mount gritter on tractor,
 using a lifting device lift the machine so the tractor's PTO shaft and machine's power input
connection are the same height related to the ground. Once this position is achieved, install the
articulated telescopic shaft. If this is not possible as the shaft is too long do as follows:
omount two sections of the articulated telescopic shaft on PTO shaft and power input
connection splines so as to keep 30mm clearance at the articulated telescopic shaft side
for a safety device to engage. Get the two shaft sections near to each other to achieve the
shortest position possible and mark lengths to be cut.
oby the same marked length shorten inner and outer guard, shorten inner and outer sliding
profile to match the guard. Other modifications of the shaft are not recommended.
oinstall articulated telescopic shaft (until safety devices are engaged) and check for
clearance.

WARNING!
If need be, shorten the PTO haft according to its operator’s manual given by
the shaft’s manufacturer (Fig. 9).

WARNING!
The articulated telescopic shaft should remain connected only during gritter
operation. During transport or any servicing operations the shaft should be
disconnected from the PTO of the tractor.
WARNING!
Operate machinery only with the articulated telescopic shafts designated for
use with that machinery. Before starting work check if all the covers (tractor,
machinery and shaft) are in place and functioning. Damage or lost elements
must be replaced with original spares. Check wether the articulated telescopic
shaft is properly installed. Never get close to rotating parts it could result in
injury or death. During servicing of the shaft or the machine the engine and
the power take-off of the tractor must be turned off. Before operating any
machinery carefully read the operating manuals of the shaft and the machine.

6.2. Adjustments
6.2.1. Adjusting clearance over transmission belt
Valve position is set on basis of digital scale (Fig. 10). Clearance between the valve (upon its
closure) and the belt should be more than 5 mm.
Prior to commissioning of SAND gritter adjust clearance over transmission belt with use of
board L(Fig. 11). Clearance between board Land the belt should be 25 mm.
WARNING!
Prior to starting the gritter, clean the clearance from any remaining ice
and iced sand.

6.2.2. Adjusting the angle of blades on spreading disk
An additional adjustment can be made by changing the angle of the blades on spreading disk
(Fig. 12). Unscrew the nut and M6 screw, turn the blade to appropriate position (1-5) and screw the
screw in the new position.

WARNING!
To obtain the optimal spread:
 use for spreading only dry and non-lumped material,
 make sure that the gritter is installed in a horizontal position,
 make sure that the baldes are in good condition, check the arrangement of
the blades and if necessary, tighten the fastening screws,
 observe the recommended working speed,
 regularly check the condition of all parts of the gritter,
 after finishing work, thoroughly clean the gritter.
6.2.3. Adjusting tensioning and position of transmission belt
 Using tensioning bolts (N, Fig. 13a) adjust belt tensioning whenever skid occurs on the
tensioning drum;
 After 15 minutes of the idle work, the belt should be located in central position on rollers.
If tape starts to come off from the drum, increase the belt’s tensioning with a bolt from the side,
to which the belt is moved,
 Belt’s tensioning range can be adjusted within 100 – 140 mm. When the belt is properly tensed,
dimension A(Fig. 13b) is 122 mm.

6.2.4. Adjusting tensioning of v-belt
- loosen two M10 bolts, which mount the disk’s base;
- adjust the belt’s tensioning with use of M12 bolt;
- tighten both bolts, which mount the disk’s base.
6.2.5. Adjusting tensioning v-belts of transmission belt’s drive
- adjust the tensioner’s support.
