SAFETY INSTRUCTIONS
Ensure that DB-8000-XL is level and secured
to floor.
Wear gloves & eye protection.
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 ou
t 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 arms.
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.
*If using a Diamond Plate kit, skip to page 9.*
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 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.

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:
***If using a Diamond Plate kit, skip to page 9***
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 besi
de 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!
Wear gloves and eye protection while operating unit!
!! WARNING !!
DO NOT disable or override the built in safety
measures. Serious injury, property damage,
or death may result.

TROUBLESHOOTING
SYMPTOM PROBLEM FIX
Arms do not move when foot
pedal is pressed.
1. Leak in air cylinder

Drain & repair cylinder, replace if needed
3. Restricted or kinked air line
Locate & correct restriction
Cylinder starts, but stalls
4. Leak in air line
Locate & repair leak
while in motion.
5. Insufficient air supply
Correct supply (80-150psi, 20-30cfm)
Arms move, but stop before
compressing spring.
1. Safety cage not in position
Ensure cage is all the way down
2. Foot valve failure
Inspect foot valve & repair/replace if needed
3. Insufficient air pressure
4. Improper setup
Increase pressure, DO NOT exceed 150psi
Straighten strut assembly
Ensure clamps are place as far apart as
possible
Arms drift instead of holding
position.
1. Air-line leakage
Find and repair line leak
2. Cylinder leakage
Perform service on cylinder
Repair/replace seals
Not able to engage clamps
on spring
1. Spring doesn’t have enough
coils
2. Spring length is too short
Remove upper clamps and replace with
optional Diamond plate adapter
(PN: 20-8000)

IN PLACE, ALIGN OPENING IN ITEM #2 WITH
BOSS ON THE SHAFT OF THE VERTICAL
ADJUSTMENT ARM. LIFT ITEM #2 INTO PLACE
BELOW THE DIAMOND PLATE THEN ROTATE
180° SO THAT THE OPENING NO LONGER
ALIGNS WITH BOSS.

INSTALLATION & USE OF OPTIONAL DIAMOND PLATE KIT (continued…)
The optional diamond plate kit (PN: 20-8000) is used on heavy duty springs, or where the assembly is not able
to be properly installed into the unit using the upper and lower claw hooks.
Double check that the diamond plate is drawn
tight to the upper arms using the vertical
adjustment knobs.
Install a double claw hook on each of the lower
two arms.
Position the strut assembly onto the lower arms
using the vertical adjustment knobs to orient the
strut assembly in a vertical position.
If the strut assembly has studs that do not align
with a pattern in the diamond plate, install the
diamond plate stud spacers over the studs on the
strut assembly.
Slowly raise the strut into position with the
compressor and once the top end (or stud
spacers) contacts the diamond plate, verify that
both lower double claw hooks are contacting the
spring.
Install (4) custom placement pins to secure the
top end of the assembly & prevent it from moving
under compression.
Compress the strut assembly.
Position the strut support weldment (third hand)
under the assembly to hold it in place.
Remove the fastener from the top of the unit and
lower the strut compressor relieving the spring.
Reverse steps to reassemble.
