 hitch,
 reflective device,
 support leg,
 spray paint (150 ml).
4.2. Spare parts
Spare parts should be ordered as per spare parts catalogue, giving full name of part, its
reference number and information from its data plate such as: machine symbol, manufacturing year,
version and serial number.
NOTE:
Use only original SaMASZ equipment and spare parts. Spare parts of
unknown origin or new made feature lower strength and have unfavourable
influence on machine’s performance and overall safety.
NOTE:
The SaMASZ co. does not bear any responsibility for damages and defects
caused as a result of applying non-original parts and equipment.
5. OPERATING GRITTER
NOTE:
Materials (fine sand, gravel, sand) used for gritting must be dry, stored under roof
and protected against dampness. Natural aggregates should be as uniform as
possible.
General requirements for road salts used in Poland are set out in
PN-86/C-84081/02. These are the following requirements:
- NaCl contents - at least 90%,
- contents of substances insoluble in water - max. 8.0%,
- water contents - max. 3.0%,
- potassium ferrocyanide contents - 20 mg/kg.
5.1. Mounting gritter to tractor
Conditions of mounting gritter to tractor
 An agricultural tractor to which the gritter is to be mounted must be fully operational.
 Gobi gritter has been designed to be used as a rear gritter, mounted on tractor's hitch or bar.
 The gritter must be equipped with agricultural hitch or lifter with bar.
 When mounting, between the machine and the tractor, no unauthorised people should be present.
Person assisting in mounting the gritter on, should be visible all the time by the tractor's operator.
The gritter can be mounted on the hitch or the bar, as shown in Fig. 4.

Operator's Manual Gritter Gobi
- 8 -
Fig. 4. Aggregating gritter: a) to hitch, b) to bar
In order to mount the gritter drive towards its hitch as near as possible, stop the tractor and
protect it against falling, and then insert the hitch eye on the gritter into hitch eye or bar on the
tractor, and connect them with pin. Then protect the pin against falling with cotter. Finally lift the
gritter's support foot.
NOTE:
The manufacturer shall not be held responsible for gritter’s damages
resulting from improper mounting to tractor.
5.2. Controlling gritter
Once the machine is mounted on the tractor, fill it with working medium. Next make sure that
spreading rate adjustment handle (Fig. 5, item A) is not in quick unload position – is pre-tensioned.
Once the above are met, the dosing mechanism can be started using lock at both hubs of drive
wheels (Fig. 5 item B). Rotary speed of the shafts is constant and proportionately dependant of the
driving speed. Spreading rate is adjusted with handle (Fig. 5, item A), as provided on information
decal.

5.3. Preparing gritter for operation
Once the gritter is properly mounted on the tractor, first check the reflection device for
visibility and damage. Then check whether on the gritter, there are no used flap rubber, damaged
elements or unscrewed bolts. If needed, replace worn and damaged elements with new ones and
tighten screws. Every time before operation, remove side guards on the gritter and lubricate
bearings on both shafts (grease ŁT 43), and during operation make sure to lubricate once every 10
hours. Check the chain tension, and if necessary tighten and lubricate the chain (mineral oil
15W40).
Fig. 6. Lubrication points on Gobi gritter
5.4. Operation
NOTE:
When spreading sand make sure to always adjust driving speed to road
conditions ahead. Do not drive faster than 15 km/h.
Gobi gritter has been designed as a precise gritter to spread sand, salt, grit, or lime. Owing to
vertical spreading system it causes no damages to cars and pose no danger to passers-by. When
spreading salt these gritters pose no danger to green areas.
Before lifting and lowering of the machine make sure that there are no unauthorised people
within its operating range.
Upon loading the gritter and setting it in proper operating position (Fig. 7) operation can be
started. Proper operating position is when the draw-bar is parallel to the ground. To enable dosing,
release locks for drive activation (Fig. 5 item B). The gritter is equipped with spreading rate
adjustment through adjustment of the pressure of rear flap onto dosing shaft with the lever .
Spreading rate adjustment is based on the operator's needs and his assessment.
WARNING!
Do not exceed maximum loading capacity of the machine!
CAUTION!
When driving across slopes the gritter may tip over!

Fig. 7. Proper spreading position
WARNING!
When driving in reverse, pay particular attention. When machine is turned at
excessive angle, it may be damaged.
5.5. Transport and standstill position of gritter
For the gritter transport turn off drive mechanism of dosing system by removing the lock from
both sides (Fig. 5 item B). For the time the aggregate of tractor and mounted gritter is in standstill,
engage the handbrake on the tractor. Once the work is completed, dismount the gritter from tractor,
empty it, protect against moving and support on a foot.
ATTENTION!
Leaving the machine with full hopper on a support foot may cause the locked
foot to move, leading to falling of the draw-bar.
6. OPERATING SERVICE
Before any operation activity:
 make sure that gritter is properly mounted to tractor,
 check condition of both rear and front flap, and if necessary, replace with new ones,
 check torque of all bolts and nuts according to Tab. 2,
 check condition of chain - tightening and wear,
 grease bearings (ŁT 43 grease) and lubricate the chain (15W40 mineral oil),
 if any torn bolts or damaged parts are found - replace them with new ones.
Upon completion of operation:
 empty hopper completely,
 clean and wash thoroughly.

7. MAINTENANCE AND STORAGE
If gritter is idle for more than two weeks, make sure to perform the following maintenance
works:
 clean and wash gritter thoroughly,
 perform any repair, adjustment, replacement of sealing or hose, if necessary,
 remove any sources of corrosion and complement any paintwork defects,

Gritter should be stored in a dry and clean place, which is inaccessible to unauthorised
personnel and animals, on even and paved ground under roof or other cover protecting it from
influence of atmospheric conditions.
8. TRANSPORT AND DELIVERY
Both carrier and driver are responsible for machine transport. All equipment and parts must be
secured for transport. In order to move the gritter onto other means of transport, follow the below
rules.
 For hoisting do use hoists with capacity bigger than the machine weight as indicated on its data
plate. It also applies to the necessary cables and chains,
 transport belts, belt suspensions, ropes cannot be damaged. Whenever damages to these parts
are found, replace these with new ones,
 When hoisting do seize the points indicated for this purpose on the machine
and labelled with a hook symbol (Fig. 8) only,
 When mounting slings, chains, clamps, etc. always bear in mind the centre of gravity of the
machine (Fig. 9),
 For seizing the machines pick lines of adequate length, so that the angle between them was no
greater than 120°, and the angle of inclination between the cable and the vertical was no greater
than 60°,
 collapsible elements should be locked in transport position,
 when relocating the machine onto another vehicle, there should be no unauthorised personnel
permitted to remain within the danger area,
 The machine should be protected from shifting on the vehicle's trailer.
