INSTRUCTIONS FOR USE

IMPORTANT: Do not use the coil spring compressor fully extended, but

adjusted to a length of approx. 200 mm. This will allow adequate travel to

expand and compress the spring.

1. Raise the vehicle to allow access to the spring.

• Make sure that the vehicle is safely and correctly supported.

2. Put the yoke (A) into the lower

part of the spring windings.

3. Insert yoke (B) into the upper part

of the spring windings.

• Make sure that the spring

windings sit between the inner

and outer rims of the yoke.

4. Insert the body of the spring

compressor up through the spring.

• The hexagonal drive nut must

be facing downwards.

5. Guide the compressor through

the lower yoke (A) and up into the

upper yoke (B),

6. When the compressor has passed

through the upper yoke turn the

body through approx 50° so it

locates in the locking grooves on

the yoke as shown.

• Make sure that the spring is

correctly placed within both

yokes and yokes are correctly

aligned with the compressor

body.

WARNING: MEASURE THE OUTER DIAMETER OF THE SPRING TO BE

COMPRESSED AND SELECT THE CORRECT SET OF YOKES.

WARNING: ENSURE THAT THE COIL SPRING TO BE COMPRESSED IS FREE

FROM DIRT AND GREASE WHERE THE YOKES WILL BE IN CONTACT WITH IT

7. Use a 19mm hex socket to turn the hexagonal drive nut until the yokes are

firmly in contact with the spring.

8. Now continue to compress the spring.

9. Remove the spring and compressor assembly from the vehicle as soon as

you have attained sufficient compression.

10. With the spring supported turn the hexagonal drive nut in the opposite

direction and remove the compressor and yokes from the spring.

11. To re-mount the spring, reverse the procedure.

WARNING: AIR TOOLS MUST NOT BE USED TO ADJUST THE SPRING

COMPRESSOR. USE OF AIR TOOLS WILL INVALIDATE THE WARRANTY.

WARNING: DO NOT ALLOW THE SPRING WINDINGS TO TOUCH. DO NOT

ALLOW THE COMPRESSOR TO REACH THE LIMIT OF ITS TRAVEL IN EITHER

DIRECTION.
