New Holland W130, Workshop Manual, Page: 12 / 41

GENERALITIES
Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual)
0 - 6 W130/W130TC
ELECTRICAL SYSTEM
Always disconnect the batteries prior to any intervention
on the machine or its electrical system (cleaning, repair,
maintenance).
Should booster batteries be used, remember to connect
ends of the booster cables in the proper manner: (+) to (+)
and (-) to (-). Do not short-circuit terminals. Thoroughly
follow instructions given in this Manual.
Before any intervention, make sure that the battery isolator
switch is off.
BATTERY GAS IS HIGHLY FLAMMABLE. Leave the bat-
tery compartment open during recharging to improve
ventilation. Never check battery charge by placing metal
objects across the posts. Keep sparks or open flames away
from batteries. Do not smoke near the battery to prevent
explosion hazard.
Before any intervention, make sure that there are no fuel
or electrolyte leakages. If any, correct prior to proceeding
with further work. Do not recharge batteries in confined
spaces. Ensure proper ventilation is provided to avoid
accidental explosions due to build-up of gas released
during charging.
HYDRAULIC SYSTEM
Pressure fluid escaping from a very small hole can be
almost invisible and still have sufficient force to penetrate
the skin. Always check any suspected pressure leaks
using a piece of cardboard or wood. DO NOT USE HANDS.
If injured by escaping fluid, obtain medical attention imme-
diately or serious infection or reaction may develop.
Stop the engine and relieve all system pressure before
removing panels, housings, caps, plugs or covers.
Always use gauges of adequate capacity (end-of-scale
reading) and follow recommended procedures.
TOOLS
Always keep head, body, limbs, feet, or hands away from
bucket, blade, or ripper when in the raised position. Prior
to any intervention, install all safety devices according to
current regulations. In case the attachment is to be oper-
ated through the machine hydraulic system for mainte-
nance purposes, remember to do so only while sitting in the
driver's seat. Make sure that nobody is within the machine
operating range. Before operating the attachment, alert
people by sounding the horn and by voice. Raise the
attachment slowly.
SAFETY RULES
Do not use the machine to transport loose objects, unless
proper devices to this purpose are provided.
Clutches and brakes of this machine as well as auxiliary
devices and attachments (such as drive cylinder or winch
control valves) should always be properly adjusted in
accordance with the instructions provided by the Manufac-
turer. Never perform adjustments with the engine running,
except when this is specifically required by the relevant
procedures.
TYRES AND WHEELS
Make sure that the tyre inflation pressure corresponds to
specifications issued by the Manufacturer. Regularly
check inflation pressure.
Should pressure be changed, do this while staying on the
tyre side and at a safe distance.
Pressure checks should always be carried out with the
machine unloaded and cold tyres.
Never use reconditioned tyre rims, since possible
weldings, incorrect heat-treatments or repairs can
weaken the wheels and cause damages or failures.
Do not cut, nor weld rims with inflated tyres installed.
The spare tyre should be inflated only enough to keep the
rim components assembled. Remember that when not
installed on the disc, a tyre inflated to maximum pressure
can explode.
Therefore, maximum care must be taken when handling a
fully inflated tyre.
Before servicing tyres, block all wheels, front and rear. After
jacking up the machine, block it in the raised position using
suitable stands conforming to current safety regulations.
Deflate the tyre before removing objects from the tyre tread.
Never inflate tyres with flammable gas: explosions and
severe bodily injuries may result.
When starting your work shift, check for loose wheel or rim
bolts and brackets and retighten to correct torque as
necessary.
