OPERATION / MAINTENANCE
Handled correctly the LPS 55 Scabbler/
Tamper will work quickly and efficiently.
Gloves and personal protective equipment
must be worn when using this tool.
Care must be taken to avoid damaging or
tripping over the air hose.
Maintenance
Only a competent person, in a suitably
equipped workshop, must carry out
maintenance. Disconnect the tool from the
air supply before carrying out any of the
following operations.
Dismantling
Clean all debris from the exterior of the tool.
Handle/Valve Body servicing
Hold main shaft in a vice, about three
inches (75mm) away from the cylinder
assembly, slacken off the locknut (10)
using a 38mm (1½) wrench on the spanner
flats. Retain the sealing washer (10a). Then
unscrew the valve body assembly from the
main shaft.
Secure the valve body assembly (14) in a
vice, holding on the main body casing.
Using a suitable spanner unscrew the
adapter (19) from the valve body, remove
the spring (21) and spring seat (20),
retrieve the valve stem (24) with its
O’Rings. Using a 6mm punch, drive out the
throttle lever pivot pin (25) and withdraw the
throttle lever (12).
Piston and Cylinder removal
(Threaded Piston)
Hold the Scabbler head (7) or Tamper foot
securely in a vice, then using a 1¼” (32mm)
spanner on the piston flats, unscrew the
Scabbler head or Tamper foot. Using a
suitable wrench on the spanner flats on the
cylinder remove the cylinder and then the
piston (6) from the cylinder (2). Remove the
piston O' Ring (not shown in the exploded
diagram) and remove cylinder wiper seal
(5) and O' Rings (3) and (4).
(Pin fit Piston)
Hold the Scabbler head (7) or Tamper foot
securely in a vice, then using a 12mm
punch drive out the retaining spiral pin (8)
and remove the Scabbler head or Tamper
foot. Using a suitable wrench on the
spanner flats on the cylinder remove the
cylinder and then the piston (6) from the
cylinder (2). Remove cylinder wiper seal (5)
and O' Rings (3) and (4).
Assembly
Before any assembly takes place, ensure
all parts are clean and have a film of air tool
oil lubrication unless otherwise stated.
Avoid lubricating oil contaminating the
threads of the cylinder (2), the main shaft
(9) and the valve body (14). These will
require securing with a thread-locking
adhesive. It is good practice to renew all the
O'Rings. Replace any parts showing signs
of wear; paying particular attention to the
small bore of the cylinder.
Handle/Valve Body Assembly
Apply general-purpose bearing grease to
the valve stem, insert valve stem (24) with
its O'Rings (22) and (23) into valve guide
followed by the spring (21). Screw in
adaptor (19) by hand and using a
32mm (1¼) spanner fully tighten. Using a
6mm punch align the hole in the throttle
lever (12) with the holes in the valve body
(14). Using a small hammer fit the throttle
lever pin (25).
Piston and Cylinder Assembly.
(Threaded Piston)
Fit a new wiper seal (5) and O' rings (3)
and (4) to the appropriate small and large
grooves on the cylinder (2). Fit a new
O' ring on to the piston (6) and insert into
the cylinder. Screw on the Scabbler head
(7) or Tamper foot until it butts up against
shoulder of piston. Hold in a vice, gripping
on the Scabbler head or Tamper foot using
the spanner flats. Fully secure using a
suitable wrench on the piston’s spanner
flats to a torque of 500lbs/ft (678Nm).
Ensure that the threads of the cylinder and
casing assembly are clean and free of oil;
apply a bead of Loctite 243 or similar to the
first few threads of the cylinder. Hold the
casing assembly in a vice using the flats
provided and screw in the cylinder
assembly by hand, using a suitable wrench
on the spanner flats on the cylinder tighten
to a recommended torque of
135Nm (100 lbs/ft).
Piston and Cylinder Assembly.
(Pin fit Piston)
Fit a new wiper seal (5) and both O' rings
(3) and (4) to the appropriate small and
large grooves on the cylinder (2). Insert the
piston (6) into the cylinder. Fit the Scabbler
head (7) or Tamper foot until it butts up
against the front face of the piston (6). Align
the holes in the piston and Scabbler head
or Tamper foot. A ” Allen Key is a good
fit for this purpose or use a suitable piece of
wooden dowelling. Hold the spiral pin (8)
with a pair of pliers to avoid hitting the
fingers, and then using a hammer, drive in
the spiral pin centrally to secure the
Scabbler head or Tamper foot.
Ensure that the threads of the cylinder and
casing are clean and free of oil; apply a bead
of Loctite 243 or similar to the first few threads
of the cylinder. Hold the casing assembly in a
vice on the flats provided and screw in the
cylinder assembly by hand. Using a suitable
wrench on the spanner flats on the cylinder
tighten to a recommended torque of 135Nm
(100 lbs/ft).
Body Assembly
Hold main shaft in a vice, about three inches
(75mm) away from the valve assembly.
Ensure sealing washer (10a) is in place and
that the threads of the valve body (14) and
main shaft (9) are clean and free of oil; apply
a bead of Loctite 243 or a similar product to
the first few threads of the Handle and screw
on the valve body until hand tight.
Tighten the locknut (10) using a 38mm (1 ”)
wrench on the spanner flats.
Machine Storage
Storage: over 3 months.
Clean the outside of the machine and inspect
the piston and cutterhead for wear, replace
any worn parts as required. Put a liberal
amount of lubricant into the air inlet of the tool
and run the tool for a few seconds to disperse
the oil around the tools internal components.
Lubricate the exposed part of the piston and
cylinder. (See recommended lubricants)
Cover the machine to protect it:
Store the machine in a dry place.
When next used, continue as per “Starting
work section”.
Disposal
When the tool and its accessories are taken
out of service for disposal, it is recommended
that: - It is dismantled into component form,
segregated according to material composition
and disposed of using waste recycling
processes specified by local regulations.

(K)** Equals the factor of uncertainty, which allows for variations in measurement and production.
Vibration data figures are tri-axial , which gives total vibration emission.
Risk of Hand Arm Injury
Because of various factors, the range of vibration emission during intended use can vary.
The vibration is dependent on the task, the operators grip, and feed force employed etc.
