1 Service and maintenance
1.1 Safety rules during service
NOTICE
Read all signs and instructions on the machine and in
the safety regulations in the Instruction Manual before
you start servicing the machine.
Each of these contains important information about
handling and service.
Servicing which is not done correctly can present risks.
Make sure that you have enough knowledge, the correct
information, the correct tools and the correct equipment in
order to be able to carry out the service correctly. Repair or
replace broken tools or broken equipment.
You are not allowed to service the machine unless you
have the correct knowledge to do the work.
When you handle oil or fuel you should take measures to
avoid waste. Oil which is dumped on the ground will cause
damage to the environment and may also cause fire. Used
oils and fluids should always be taken care of by an
authorised company.
If you plan to install a comms radio, mobile phone or
similar equipment then the installation must be done
professionally in order to eliminate interference with
certain electronic components controlling the machine.
NOTICE
Always switch off the engine during service.
WARNING
Risk of serious crushing injury or fatal accident!
Always switch off the engine before releasing the cab to
tip it up.
Never go under a tipped-up cab unless it is propped up.
Ensure that the cab is propped up if you need to go
under it!

1.1 Safety rules during service
Gremo1050F4 Service and maintenance
manual
WARNING
During all work on the machine, remember the risk of
slipping. You should always use a safety helmet, safety
goggles, gloves, safety boots, breathing protection and
other necessary protective equipment when required.
WARNING
The bogie lift can be used as a lifting aid during service
and repairs, but always prop up the machine.
WARNING
When you lift or prop up the machine or parts of the
machine, make sure that the equipment you use is
intended for this purpose, is appropriately dimensioned,
and cannot slip or tip over!
CAUTION
When you are about to change the engine oil, hydraulic
oil or transmission oil: remember that the oil may be hot
and can cause burns. Avoid contact with skin and note
that oil vapours can cause irritation to airways.
CAUTION
The exhaust pipes are very hot and can cause serious
burns!
NOTICE
In case of hose breakage: connect the vacuum pump
(additional equipment) so that unnecessary oil does not
leak out!

Gremo1050F4 Service and maintenance manual 1 Service and maintenance
1.2 Service and maintenance
1.2 Service and maintenance
Preventive maintenance measures are divided into time
intervals: daily checks (every 8-10 operating hours),
weekly checks every 50 operating hours and checks every
500, 1,000, 2,000 and 5,000 operating hours.
NOTICE
Regular servicing, and maintenance and servicing
during the guarantee period, i.e. the first 2,000 operating
hours, are described in the Service and Maintenance
Manual.
The daily maintenance includes a systematic inspection of
all screw joints. This measure is particularly important
when the machine is new or has been dismantled. The
more accuracy and care you put into the inspection at this
stage, the less is the risk of loose screw joints in the future.

1.4 Working with oils
CAUTION
All work where you may get into contact with oil involves
a risk of skin trouble, e.g. eczema. The risk is greatest in
the case of hydraulic oils, but there is also a risk with
other types of oil. Careful hygiene is therefore always of
great importance!
Some hints to remember and observe:
• Avoid contact with oil, especially hot oil!
• If your skin has been exposed to oil, clean it as soon as
possible with water and soap, or with a suitable washing
cream and water.

1.5 Oil, requirement specification
• Use protective gloves! Wash your hands before putting
the gloves on. A protective cream on your hands will
make it easier to clean them later.
• Don’t keep any oil-stained rags in your pockets!
• Change oil-stained clothes for fresh ones!
• Always keep an extra overall easily available e.g. in
your car or work-shed. Not in the machine where it
easily gets dirty.
• Cuts and small wounds must be treated immediately by
cleaning and applying dressings!
• Avoid breathing oil fumes!
• Wash your hands and arms at every meal break, or as
often as possible!
NOTICE
Oil drums standing outdoors collect water in the lid, and
this water can run down into the oil.
1.5 Oil, requirement specification
Fig. 1 Lubricating oil viscosity
Water-damaged oil results in machine breakdown.
Store oil drums lying horizontally under a roof.
As the viscosity of lubricating oil is dependent on
temperature, the choice of viscosity grade (SAE grade)
should be governed by the ambient temperature prevailing
at the engine operating site.
The optimum operating conditions are attained if you use
the oil viscosity figure shown here as a guide.
Should the temperature fall temporarily below the limits,
cold starting may be affected but the engine will not be
damaged.
In order to keep wear to a minimum, do not exceed the
operating limits for extended periods of time.
Oil changes dictated by the seasonal changes can be
avoided by using multi-grade lubricating oils. Multi-grade
oils also reduce fuel consumption.
Part Oil/lubricant

Engines should be lubricated with MOTOREX engine oil or
equivalent which meets the manufacturer's specifications, see sub-
supplier's documentation for diesel engine.

DANGER
Never stand in front of a tyre while it is being inflated! Do
not exceed the prescribed tyre pressure, which should
be checked at ambient temperature. If there is a change
to a different version of tyre or wheel rim, a different tyre
pressure may apply — contact Gremo.
Danger!
To avoid serious accidents, always follow directions for
inflating tyres.
WARNING
Before a wheel is replaced, the tyre must first be emptied
of air.
Risk of tyre explosion! Danger!
Empty the tyre by removing and dismantling the valve.
WARNING
If the wheel rim is damaged, handling the wheel is
extremely dangerous!
Risk of tyre explosion! Danger!
Have wheels replaced by a service department
authorised to handle tyres!
WARNING
Antifreeze can be explosive When tyres are inflated, the
air must therefore not contain any antifreeze.

manual
• Use max. pressure on difficult and stony ground.
NOTICE
You should check tyre pressure regularly. Remember to
check tyre pressure at low temperatures, the pressure is
then lower than in hot summer weather.
NOTICE
The machine must not be loaded when the tyre pressure
is checked.
Low tyre pressure, advantages:
• Good comfort.
• Large contact surface.
• Lower ground pressure
• Increased traction
• Reduced formation of wheel tracks.
Low tyre pressure, disadvantages:
• Reduced stability.
• Increased risk of hose damage/wear.
High tyre pressure, advantages:
• Gives better protection against tyre side damage.
• Increased stability.
• Requirement for track use.
High tyre pressure, disadvantages:
• Reduced comfort.
• Increased risk of cutting and puncture damage.
• Increased sensitivity to spot loads.
• Increased formation of wheel tracks
• Poorer grip.
1.10.1 Filling of fluid in forestry tyres
Fig. 2 Level, filling tyres with fluid
14
The tyres can be filled with fluid to increase the machine’s
stability and traction
Gremo recommends filling 50% of the tyres’ volume.
Maximum permitted is 75%.
The fluid should consist of water. At temperatures below
zero, the fluid used should be a mixture of calcium
chloride/water or glycol/water
Gremo1050F4 Service and maintenance manual 1 Service and maintenance
1.10 Tyres — Air pressure: Manufacturer’s
recommendations
By turning the wheel and pressing in the valve needle, it is
easily possible to determine whether the tyre is filled to
75% or 50% fluid.
Calcium chloride increases the fluid’s density by up to 1.2
kg/litre in a 35% blend.
Fluid-filled tyres are less elastic owing to their smaller air
volume and are therefore more vulnerable to spot loads.
Rolling resistance and the dynamic forces acting on the
wheel rims and suspension components are also higher.
NOTICE
When changing tyres, use the right kind of tyre paste
intended for heavy vehicles or forestry machinery.
Otherwise, the tyre may slip on the rim.
