4. ASSEMBLY
REFER TO ATTACHED PARTS DIAGRAM
4.1.
Attach the brackets to the base using the fixings shown on the parts diagram.
4.2.
Attach the pedal to the pump and secure.
4.3.
Attach the chains, one to each side of the upper strut support, refer to (fig.1).
IMPORTANT: secure the machine to the floor. The brackets are drilled to
accept bolts which should be secured to suitable fixings.
4.5
MOUNTING THE YOKES (See fig.1)
4.5.1
Push the required yoke onto the yoke mounting spigot.
4.5.2
Secure with the yoke retaining pin and insert the 'R' clip.
4.5.3
Repeat to secure the lower yoke with its pin and 'R' clip.
4.5.4
Make sure that the correct size yokes are installed with the bottom yoke facing
up and top yoke facing down.
5. AIR SUPPLY
WARNING! Ensure air supply is clean and does not exceed 120psi (8.3bar).
‰
Too high an air pressure and unclean air will shorten the life of the unit due
to excessive wear, and may be dangerous causing possible damage and/or
personal injury.
5.1.
Connect the air control valve to the air supply hose.
5.2.
For recommended connection, see diagram.
5.3.
Drain the air supply tank daily and clean the air inlet filter screen weekly.
5.4.
Line pressure should be increased to compensate for long air hoses (over 8mtr).
5.5.
Keep hoses away from heat, oil and sharp edges. Check for wear and make sure that all connection are secure.
6. OPERATION
6.1.
COMPRESSING A STRUT SPRING
6.1.1.
NOTE: Before removing the strut from the vehicle it is recommended that the upper strut
locking plate nut is loosened a quarter turn. DO NOT loosen more than a quarter turn.
6.1.2.
With the strut and spring removed from the vehicle, select the most suitably sized yoke
according to the size of the spring and fit it onto the compressor using the locking pin
to hold it in position (fig.1).
6.1.3.
Move the upper support to the required height in order to accommodate the spring.
Do this by releasing the two upper yoke locking pins (fig.1), moving the support and
replacing the pins, ensuring that the 'R' clips are inserted.
6.1.4.
Place the spring between the yokes, rotate into place, then wrap the safety chains
around the spring.
6.1.5.
Position one chain around a coil protruding above the top yoke (fig.2A) and the other
chain below the bottom yoke (fig.2B). Check that neither chain could be trapped between
the coils. Ensure that the chains are as tight as possible.
6.1.6.
Apply light hydraulic pressure with the pump pedal and check that the spring is seated correctly.
▲
DANGER! Stop compressing the spring before the coil windings touch/bind.
WARNING! If the spring/strut is not located correctly in the yokes, it is possible that
‰
the strut top retaining cap could be subject to sideways forces. Watch closely as the
spring reaches it's final phase of compression and ensure the top cap assembly
rotates freely before attempting to remove it.
6.1.7.
If the spring is seated correctly, use either the air control valve or pedal to continue
compressing the spring, standing to the side of the machine.
6.1.8.
Compress the spring gradually, making sure that the spring stays seated in the yokes.
6.1.9.
When compressing conical springs; the centre line of the spring should remain
parallel to the compressor body.
WARNING! Check that the nut is free by using a metal or wooden item.
‰
DO NOT check with fingers or hands.
8
6.2.
It is recommended that a purpose-made strut nut socket is used to remove the nut.
6.2.1.
Support the shock absorber to prevent it falling clear when released.
DO NOT leave the spring compressed, release the pressure on the spring if it is to be
8
left for any time.
6.2.2.
Decompress the spring by pressing the release valve pedal (next to the pump pedal) gradually.
6.3.
FITTING A STRUT SPRING
6.3.1.
Offer the new strut spring up to the compressor's yokes and fit it in the same position as that of the old spring.
6.3.2.
Position the lowest coil of the spring in the lower yoke and rotate the spring, so that the coil is held as low as possible. Position the
upper yoke below the top coil. Ensure that the coil is placed inside the recesses of the yokes to ensure that the coil will not break free
under compression.
NOTE: There must be coils free at either end to allow them to seat on the strut plates, without the strut and compressor yokes interfering.
6.3.3.
Position one chain around a coil protruding above the top yoke (fig.2A) and the other chain below the bottom yoke (fig.2B). Check that
neither chain could be trapped between the coils. Ensure that the chains are as tight as possible.
▲
DANGER! Stop compressing the spring before the coil windings touch or bind.
6.3.4.
WARNING! Keep hands away from spring.
6.3.5.
Compress the spring using the correct pedal on the foot control unit, ensuring that the spring is securely held in place within the clamp
recesses at all times. When the spring is compressed sufficiently, fit the strut top plate to the strut, and using a new nut, secure
it in position.
6.3.6.
Decompress the spring carefully and slowly, using the pedal on the foot control unit, ensuring the spring is located correctly into the
strut top plate.
