OPERATION
Installing the Strut Spring Compressors
For the purposes of this manual, it is assumed you will be removing a strut spring from a MacPherson Strut
Assembly which has been removed from the vehicle.
WARNING: To prevent serious injury and/or property damage, only use this product to compress strut
springs.
Step 1: Place the Strut Assembly down on a workbench or other solid work surface.
Step 2: Examine the strut spring inside the Strut Assembly. You will need to identify areas at each end of
the strut spring to attach the PULLER HOOKS of the Strut Spring Compressor. There needs to be
enough space between the coils for the PULLER HOOKS to t between and still allow you enough
compression to collapse the spring enough for safe removal. Ideally you will place the PULLER
HOOKS towards the outer ends of the coil spring.
Step 3: Adjust the NUT (#4) to give you the ability to move the PULLER HOOK (#1) along the SUPPORT
BAR (#3) as shown in Figure 1.
