3. Hazards that may arise
from the tool
Before each use, check the HAZET
engine timing tool set for full functional
efficiency and damage. If functionality
is not guaranteed after this test or if damage is
discovered, do not use the tool. If you use the
tool despite full functionality not being guaran-
teed, this poses a risk of serious injury, health
problems and material damage. Defective
tools may cause severe injury.
I n order to avoid injury or damage, it
is essential that the following funda-
mental safety guidelines will be
observed:
CAUTION:
Incorrect or out of phase camshaft
timing can result in contact
between valves and pistons caus-
ing damage to the engine. Always ensure
the correct tools are used and that the
vehicle manufacturer's procedures are
adhered to.
• Before starting to work, disconnect the
battery's negative terminal.
NOTE:
B efore disconnecting the battery,
ensure that the vehicle owner has a
record of the car radio code.
• Any vehicle "jacked up" or raised above
ground must be adequately supported with
axle stands, ramps etc.
• Wear well-fitting protective clothing
and safety glasses. Engines have
rotating components, so avoid
wearing loose clothing, jewellery
etc. which can get caught up in
the engine moving parts.
• Always account for tools being used.
Do not leave them in or near the engine
when turning the engine over, or when the
job is finished.
Parts that are not fixed can be hurled
around and may cause severe injury or
death to persons in the work area.
Objects may be damaged.
• Do not use the locking device set to block
the camshaft when loosening or tightening
the camshaft bolt.
Maintenance work on engines must be carried out only by experienced mechanics.

For your safety
Always wear personal protective equipment.
• The timing belt must not be used for locking
the camshaft sprocket when slackening the
nuts.
• Do not forcibly twist a new belt or bend it
through a radius of less than 25 mm.
• Never lever or force the timing belt onto the
sprockets.
• Check free running of tensioner roller,
guide roller(s) and water pump.
• Check engine for leakages, if detected
eliminate them.
• Replace old timing belts with a new one and
ensure that it has the correct teeth profile.
• Ensure timing belt tension is correctly
adjusted (please follow the instructions of
the manufacturer).
• Observe torque specifications (please follow
the instructions of the manufacturer).
• Pay attention to the timing belt's direction of
rotation which is indicated by an arrow.
• Do not reuse used timing belts. Always fit a
new one.
• If the timing belt shows damage, find out
origin and remedy deficiencies.
• Do not use solvents or cleaning fluids like
thinner or benzine on belts, sprockets etc.
• Do not twist, bend or reverse the timing belt
for inspection.
• The engine must only be turned in the nor-
mal direction of rotation, unless otherwise
noted by the vehicle manufacturer.
• Only use parts, attachments and acces-
sories recommended by the manufactur-
er.
• Repair work must be carried out exclu-
sively by authorised persons.
• Only use the tools at places that are governed
and regulated by applicable provisions for
work areas.
• For safety reasons any modification of HAZET
tools is strictly forbidden. Any modification
of the tool will result in immediate exclusion
from warranty and liability.
