SAFETY NOTICE 00
GENERAL PRECAUTIONS 00
Mistakes in operation are extremely dangerous. Read the OPERATION & MAINTENANCE MANUAL carefully BEFORE
operating the machine.
1. Before carrying out any greasing or repairs, read all the precautions given on the decals which are fixed to the machine.
2. When carrying out any operation, always wear safety shoes and helmet. Do not wear loose work clothes, or clothes with
buttons missing.
• Always wear safety glasses when hitting parts with a hammer.
• Always wear safety glasses when grinding parts with a grinder, etc.
3. If welding repairs are needed, always have a trained, experienced welder carry out the work. When carrying out welding
work, always wear welding gloves, apron, glasses, cap and other clothes suited for welding work.
4. When carrying out any operation with two or more workers, always agree on the operating procedure before starting.
Always inform your fellow workers before starting any step of the operation. Before starting work, hang "UNDER
REPAIR" signs on the controls in the operator's compartment.
5. Keep all tools in good condition and learn the correct way to use them.
6. Decide a place in the repair workshop to keep tools and removed parts. Always keep the tools and parts in their correct
places. Always keep the work area clean and make sure that there is no dirt or oil on the floor. Smoke only in the areas
provided for smoking. Never smoke while working.
PREPARATIONS FOR WORK 00
1. Before adding oil or making repairs, park the machine on hard, level ground, and block the wheels or tracks to prevent the
machine from moving.
2. Before starting work, lower blade, ripper, bucket or any other work equipment to the ground. If this is not possible, insert
the safety pin or use blocks to prevent the work equipment from falling. In addition, be sure to lock all the control levers
and hang warning signs on them.
3. When disassembling or assembling, support the machine with blocks, jacks or stands before starting work.
IMPORTANT SAFETY NOTICE 00
Proper service and repair is extremely important for the safe operation of your machine. The service and repair techniques
recommended and described in this manual are both effective and safe methods of operation. Some of these operations
require the use of tools specially designed for the purpose.
To prevent injury to workers, the symbol is used to mark safety precautions in this manual. The cautions
accompanying these symbols should always be followed carefully. If any dangerous situation arises or may possibly arise,
first consider safety, and take the necessary actions to deal with the situation.
WARNING! Never modify, weld, cut, or drill on any part of a ROPS structure. Doing so may weaken the
structure which could lead to possible failure in a rollover situation
4. FOREWORD SAFETY
00-4 c SK1020-5N, SK1020-5NA
4. Remove all mud and oil from the steps or other places used to get on and off the machine. Always use the handrails, lad-
ders or steps when getting on or off the machine. Never jump on or off the machine. If it is impossible to use the handrails,
ladders or steps, use a stand to provide safe footing.
PRECAUTIONS DURING WORK 00
1. When removing the oil filler cap, drain plug or hydraulic pressure measuring plugs, loosen them slowly to prevent the oil
from spurting out. Before disconnecting or removing components of the oil, water or air circuits, first remove the pressure
completely from the circuit.
2. The water and oil in the circuits are hot when the engine is stopped, so be careful not to get burned. Wait for the oil and
water to cool before carrying out any work on the oil or water circuits.
3. Before starting work, remove the leads from the battery. ALWAYS remove the lead from the negative (-) terminal first.
4. When raising heavy components, use a hoist or crane. Check that the wire rope, chains and hooks are free from damage.
Always use lifting equipment which has ample capacity. Install the lifting equipment at the correct places. Use a hoist or
crane and operate slowly to prevent the component from hitting any other part. Do not work with any part still raised by
the hoist or crane.
5. When removing covers which are under internal pressure or under pressure from a spring, always leave two bolts in
position on opposite sides. Slowly release the pressure, then slowly loosen the bolts to remove.
6. When removing components, be careful not to break or damage the wiring, Damaged wiring may cause electrical fires.
7. When removing piping, stop the fuel or oil from spilling out. If any fuel or oil drips on to the floor, wipe it up immediately.
Fuel or oil on the floor can cause you to slip, or can even start fires.
8. Gasoline or other fuels should never be used to clean parts. Clean part with appropriate solvents.
9. Be sure to assemble all parts again in their original places. Replace any damaged part with new parts.
• When installing hoses and wires, be sure that they will not be damaged by contact with other parts when the machine
is being operated.
10. When installing high pressure hoses, make sure that they are not twisted. Damaged tubes are dangerous, so be extremely
careful when installing tubes for high pressure circuits. Also check that connecting parts are correctly installed.
11. When assembling or installing parts, always use the specified tightening torques. When installing protective parts such as
guards, or parts which vibrate violently or rotate at high speed, be particularly careful to check that they are installed
correctly.
12. When aligning two holes, never insert your fingers or hand. Be careful not to get your fingers caught in a hole.
13. When measuring hydraulic pressure, check that the measuring tool is correctly assembled before taking any
measurements.
14. Take care when removing or installing the tracks of track-type machines. When removing the track, the track separates
suddenly, so never let anyone stand at either end of the track.
15. When jump starting the machine, only use a machine of similar size and voltage. Never use a arc welder or other electrical
generating equipment to jump start the machine. Carefully review the safety and procedures for jump starting the
machine.

STRUCTURE, FUNCTION AND
MAINTENANCE STANDARD DRIVE MOTOR SYSTEM
12Motor Operations
Description
The drive motor consists of:
• 2-speed hydraulic motor
• Selector valve
• Reduction gearing
Motor Function
The hydraulic drive motor is an axial piston type motor that converts hydraulic energy supplied by the main hydraulic pump
into usable rotary motion.
Operation
The hydraulic oil arriving from the selector valve is sent on to the valve
plate (1). When the oil is sent to port “A” of the valve, it flows into the
corresponding port on the cylinder block (2) and presses against the
pistons (3). This pressure is converted into rotary motion by a swash
plate (4) and transmitted to the shaft (5). The shaft and the cylinder
block have been integrated into one piece by means of spined teething.
The return oil is sent to the pump through port “B”. Rotation in the
opposite direction is achieved by sending the oil to port “B” instead of
to port “A”.
Varying The Displacement
The swash plate (4), which has two surfaces “A” and “B” on the side opposite the sliding side for the shoes (6), is supported
by two bearings (7) attached to the body of the motor (8). The position of the bearings is eccentric with respect to the axis of
the shaft and when running at a low speed the surface “A” remains in contact with the body of the motor through the pressure
exerted by the pistons (3) and by the force of a spring (9) mounted in the cylinder block (2). The angle of the swash plate is α.
When an increase in speed is demanded, the oil is sent under pressure to the command piston (10). The command piston
(10) moves to the left until the surface “B” makes contact with the housing and the angle of the swash plate becomes β (the
displacement of the motor is reduced).
