SAFETY
Improper operation can cause serious
injury or death.
Pre-operation
This machine is designed for compacting dirt and
aggregate materials only. NEVER use this
machine for any other purpose.
Read the operator’s manual for the “Skid Steer
Loader.”NEVER allow untrained people to
operate.
Operating instructions must be given to everyone
before operating this attachment and at least once
a year thereafter in accordance with OSHA
regulations.
NEVER exceed the maximum recommended input
power or speed specifications for the attachment.
Over-powering or over-speeding the attachment
may cause personal injury and/or machine
damage.
Keep all shields, guards, and covers in place.
Do not modify equipment or add attachments that
are not approved by Erskine Attachments LLC.
Use adequate safety warning lights and devices as
required by local regulations. Obey all local laws
and regulations regarding machine operation on
public property.
Make sure the area being compacted does not
contain utilities or structures that could be
damaged by vibration.
Depending on the loader and application, this
attachment may increase whole-body or hand-arm
vibration exposure to operators. To evaluate the
potential health effects of those regularly exposed,
perform an assessment according to applicable
ANSI and/or ISO human vibration standards.
Operation
Always wear eye protection that meets ANSI z87.1
standard or use with a loader enclosure that
provides similar protection.
Hydraulic connections may be hot after use. Use
gloves if connecting or disconnecting after use.
Check and be sure all operating controls are in
neutral before starting the engine.
Operation (continued)
Keep people away from loader and attachment
when in use. This attachment has rotating parts.
Depending on how this attachment is used, dust
can be created. Prolonged exposure to dust can
cause chronic and acute health problems. A
NIOSH-approved respirator may be required.
NEVER operate near embankments or terrain that
is so steep that rollover could occur.
Always stay in the operator position when using
the attachment.
Before leaving the operators position, disengage
hydraulic drive, lower the attachment to rest flat on
the ground, stop engine, set park brake, and wait
for all motion to stop.
NEVER clear debris while engine is running.
Avoid High Pressure Fluids Hazard
Escaping fluid under pressure can
penetrate the skin causing serious
injury.
Avoid the hazard by relieving the
pressure before disconnecting
hydraulic lines.
Use a piece of paper or cardboard, NOT BODY
PARTS, to check for suspected leaks. Wear
protective gloves and safety glasses or goggles
when servicing or performing maintenance on
hydraulic systems.
If an accident occurs, see a doctor immediately.
Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may
result.
Maintenance
NEVER make adjustments, lubricate, clean, or
perform any service on the machine while it is in
operation.
Make sure the attachment is serviced on a daily
basis. Improper maintenance can cause serious
injury or death in addition to damage to the
attachment and/or your equipment.

USER’S MOUNTING INSTRUCTIONS
After the initial set-up assembly is completed use the following procedure to mount the attachment to the loader.
Levers must be fully down and locked. Failure to secure wedges or pins can allow the
attachment to come off and cause injury or death.
1. Use the step, safety treads, and grab handles to
get on and off the loader and attachment.
2. Sitting in the operator’s seat, lower seat bar (if so
equipped) and fasten the seat belt.
3. Drive the loader to the rear of the attachment. Put
the loader quick attach coupler into theattachment
mounting bracket.
4. Tilt the loader coupler backward a small amount
until it is fully engaged in the attachment mounting
bracket.
5. Stop the engine and engage the park brake.
6. Secure the coupler locking mechanism that
attaches the attachment to the loader.

8
USER’S MOUNTING INSTRUCTIONS
7. Connect the hydraulic quick couplers from the
attachment to the loader auxiliary couplers and
case drain.
IMPORTANT: Wipe the ends of the hydraulic
quick couplers (both lead and loader) with a rag
to remove any possible contamination.
Contamination can cause hydraulic components
to fail and is not covered under warranty.
IMPORTANT: Make sure the quick couplers are
fully engaged. If the quick couplers do not fully
engage, check to see that the couplers are the
same size and brand. Do not force the quick
couplers together.
NOTE: See the loader’s operator’s manual for
auxiliary hydraulic specifications and connection
instructions.
NOTE: Attachment is shipped with 12FJX
(1-1/16” Female JIC Swivel) fittings on the ends
of the lead hoses.
8. Make sure the hoses are properly routed to fit
your specific loader. If the hoses are not routed
correctly, hoses may get pinched or rub on tires.
Be sure to check the hose routing through the full
range of intended motion of the attachment
before operating it.
More than one routing may be acceptable
depending on the loader. Pick the routing that
best suits your loader.
IMPORTANT: Proper hose routing is the
responsibility of the owner and/or operator.
Pinched or stretched hoses are not covered
under warranty.
Mounting is now complete and you are ready to use
the attachment. Use reverse order of above
instructions to dismount the attachment from the
loader.

OPERATING INSTRUCTIONS
1. With the operator in the seat of the loader, the
seatbelt fastened, and the seat bar lowered (if so
equipped), start the engine.
2. With the loader arms fully lowered, position the
attachment flat on the ground.
3. With the loader engine RPM at an idle, engage
the auxiliary hydraulics in continuous flow mode to
operate the attachment motor in the desired
direction.
IMPORTANT: Only engage and disengage the
auxiliary hydraulics with the loader engine RPM as
low as possible. Failure to do so will result in
premature coupler wear.
4. Gradually increase the loader engine speed until
the attachment has reached its maximum RPM.
IMPORTANT: The attachment has an RPM
limiter for the motor. When the motor has reached
this limit, DO NOT continue increasing loader
engine RPM. Doing so will increase the heat in
the skid steer hydraulic system.
5. Slowly drive forward or backward to begin
compacting in the desired direction.
IMPORTANT: Raise the attachment off of the
ground when turning.
NOTE: The direction that the motor rotates
influences how well the drum will roll along the
ground as the attachment is driven in either the
forward or reverse directions. Operate the motor
accordingly.
6. Down pressure may be applied to the attachment
by raising the skid steer’s front tires off of the
ground by 1” to 2”. This will increase the
compaction capabilities of the attachment.
However, do this in a limited fashion, as the added
weight will shorten the lifespan of the isolation
mounts.

10
ROUTINE MAINTENANCE
Lower the attachment to rest on the ground, shut down the engine, relieve the hydraulic
pressure to the attachment, set the park brake, and wait for all motion to stop before leaving the
operator’s seat to perform service of any kind.
It is the operator’s responsibility to make daily inspections of the loader and attachment for damage, loose bolts,
fluid leaks, or anything else that could cause a potential service or safety problem. Preventive maintenance is
the easiest and least expensive type of maintenance.
IMPORTANT: Bolts and set screws can loosen after initial usage. After the first hour of operation check all bolts
and set screws.
A
B
Use No. 2 lithium base gun grease when lubricating
all attachment grease fittings.
Roll the drum until the weld mark on the motor side is
up, as shown, to position the hub bearing zerks for
greasing.
Grease the two hub bearing zerks [A] and the two
flange bearing zerks [B] every 4 hours of operation.
IMPORTANT: Do not over-grease bearing. Only add
two pumps of grease every greasing interval.

ROUTINE MAINTENANCE
C
Grease the center oscillation pivot [C] every 40 hours
of operation.
NOTE: The attachment must be disconnected from
the loader in order to access this grease zerk.
Visually inspect the eight isolation mounts (four on
each end) for cuts or tears weekly.
IMPORTANT: If a rubber isolation mount has a cut or
tear, it must be replaced. If it is not replaced, the
remaining good isolation mounts will be put under
more load, which will result in premature isolation
mount failure.
IMPORTANT: Rubber isolation mounts that have a
permanent deformation should be replaced.

ROUTINE MAINTENANCE
Visually check the drive coupler rubber member for
wear every 80 hours of operation.
1. Remove the two bolts from the coupler shield.
2. Visually inspect.
3. Grab the coupler and check by hand to see if it
feels tight or loose.
NOTE: If the coupler istight, itis in goodoperating
condition. If the coupler is loose, it is a sign of
wear, and replacement may soon be required.
4. Reinstall the coupler shield.
Scraper Maintenance
As the top and bottom scrapers wear, loosen the 3/8”
bolts and slide the adjustment plate toward the drum
accordingly.
NOTE: The smooth drum scraper is shown. The
procedure to adjust the padded drum scraper is the
same as the smooth.
