SAFETY INSTRUCTIONS
Ensure that DB-8000-XL is level and secured
to floor.
Before using the device, cycle the piston to
equalize air pressure & avoid an abrupt thrust.
Be watchful of pinch points on DB-8000-XL &
strut assembly; keep extremities out of these
areas to avoid injury.
Prior to starting the compression of any spring,
it is imperative to make sure the spring is
securely placed between the opposing hooks.
If a spring begins to deflect or “bow” while
under compression, STOP, relieve the
pressure & reset the clamps closer together.
Do not place fingers or hands in, on, around,
or near moving components while strut
compressor is attached to air supply.
The DB-8000-XL features a safety valve that
prevents operation if the safety cage is not
lowered.
Never allow untrained or unauthorized
personnel to operate strut compressor.
Fully train all employees on the proper use
and care of your strut compressor.
One single finger hook and one double finger
hook should be used at the top of the unit and
also at the bottom.
MAINTENANCE INSTRUCTIONS
To avoid personal injury and damage to strut compressor, permit only qualified personnel to perform
maintenance on strut compressor(s). If you are not completely familiar with general automotive equipment
maintenance procedures, stop and contact manufacturer for instructions.
DAILY:
Inspect & repair or replace all loose bolts & damaged or broken components.
Inspect strut compressor clamp hooks & duck feet for excessive wear or damage & replace as needed.
Inspect air system for leaks and basic function.
Inspect retention arms, knobs, foot pedals, and safety cage for damage and wear, replace as needed.
MONTHLY:
Inspect support tray & spring retention arm assemblies for damage, wear & tear, and dirt and debris in
mechanism. Clean, lubricate, repair & replace components as needed.
Clean strut compressor & inspect for rust.
EVERY 2YEARS:
Disassemble air cylinders, inspect seals & lubricate seals with marine grade grease.
Check all labels on strut compressor for legibility & make sure no labels are missing. Replace as
needed.

OPERATING INSTRUCTIONS
Before operating your strut compressor, it is necessary to fully read and understand this instruction packet, &
the safety instructions. It is also recommended to dry run the strut compressor before compressing a spring to
become familiar with its operation and to help equalize air pressure in the system.
While avoiding any pinch points, follow instructions below to compress a spring:
1. Ensure supply air is connected.
2. Press the foot control pedal to actuate device
& equalize air pressure.
3. Lift safety cage & insert strut assembly into the
device. Put the low coil of the spring onto the
lower left clamp hook.
4. Adjust lower right arm according to the
diameter of the spring & turn the adjustment
knob until the hook has engaged the coil and
the strut assembly is straight up & down.
5. Adjust the upper hooks so that they capture
the spring coils at the highest point. This
allows for maximum compression.
6. Rotate handle of support plate counter
clockwise ensuring that it can move freely. Lift
the support plate and rotate it directly beneath
the strut assembly and rotate handle clockwise
to lock support plate in place.
7. Lower safety cage.
8. While holding the upper arms of the unit in
place to support the strut assembly, press the
foot control pedal & SLOWLY compress the
spring until solid contact is made on all hooks.
9. REMOVE HANDS from working area inside
the safety cage.
10. While standing beside the unit, remove any
fasteners from the strut/shock in the assembly.
This will allow the strut/shock to rest on the
support plate.
11. While supporting the strut/shock, unlock the
support plate and move it to the side.
12. Remove old strut/shock and replace with new
unit & replace fasteners.
13. Press the foot control pedal to decompress
spring and verify that all of the strut assembly
components are in the correct orientation and
position.
14. Lift the safety cage, disengage spring hooks,
and remove strut assembly.
Correct hook engagement on spring coil.
Incorrect engagement.
!! CAUTION !!
DO NOT position any body part directly above or below spring
assembly to be compressed!
!! WARNING !!
DO NOT disable or override the built in safety
measures. Serious injury, property damage,
or death may result.

INSTALLING / USING DUCK FEET
QSP supplies additional accessories to make your strut compressor more flexible. The greater the vertical
distance between the upper and lower arms, the easier it is for the unit to compress a spring. On heavier
springs, or springs with few coils, using the duck feet instead of the clamp hooks on the upper arms will help to
maximize the distance between the arms.
While avoiding any pinch points, follow instructions below to install and use duck feet:
1.
Rotate clamp hooks to align key & keyway. Hook or duck
foot will now slip off.
2.
Reverse sequence to install new clamp or duck foot.
3.
Raise the adjustment of the upper arms to their highest
position.
4.
Insert strut assembly with adapters on top of top hat.
5.
Capture at least one stud or install one bolt through the
holes of the duck feet.
6.
Compress spring as normal making sure that adapters are
securely positioned.
OPTIONAL DIAMOND PLATE ADAPTER
Optional diamond plate adapter kit (PN: 20-8000) is a rigid top plate designed to fit
over the top of most strut assemblies, taking the place of hooks or duck feet. The kit
contains (1) plate, (2) locking rings & (4) locating pins.
