Features of Virnig Mfg. Inc. Angle Broom include:
Centering swing linkage better centers broom in front of loader when angled.
Optional Hydraulic Angle with Electric Control utilizes either the machines
electrical package or an add-on control box.
15-25 GPM operating flow rate range and 2000 –3500 PSI operating
pressure range.
Easy exchange of wafers, do not have to disconnect hydraulic lines to
change wafer sections.
Hydraulic pressure relief valves on motor allow broom to operate in both
directions.
Direct drive design with replaceable drive components.
160° standard hood, optional deflector provides an additional 30° of
coverage and can be “uninstalled” by simply locking in the storage position
without removing.
Recommended for loaders with an operating capacity greater than 1500 lbs.
Initial Use
Read and understand all warning information in this manual before operating
this attachment.
Check that quick-tach on frame fits onto loader properly. Pins must engage
through 3/8” plates at bottom of quick-tach.
Slowly roll back attachment. Make sure there is no interference between
attachment and loader.
Do not connect this attachment to high flow couplers.
Make sure hoses do not pinch during roll back.
Never exceed the maximum attachment operating pressure of 3500 psi.
After Angle Broom is mounted to the loader, lift or roll back the Angle Broom
so the storage stands are not contacting the ground. Flip storage stands
into “storage”position before operation of the Angle Broom.
With the Angle Broom off of the ground, engage the auxiliary hydraulics
using the “detent” position on the machine. Check the rotation of the broom
(broom should be sweeping away from the machine.) If this rotation does
not match the “detent” position of your machine, switch the couplers on the
lead hoses.
If Angle Broom is equipped with manual angle, swing the broom head
through its cycle to check that the lead hoses do not bind or catch anywhere.
Make sure the broom is not operating and the machine is shut off when
changing the broom angle manually.

Initial Use (continued)
If the Angle Broom is equipped with hydraulic angle, with the broom running
in the sweeping direction, engage the electrical controls and cycle the broom
head from side to side and check that the lead hoses do not bind or catch
anywhere. Broom will not angle when the broom is running in reverse.
Do not storeAngle Broom with weight on the wafers as this may deform the
bristles reducing the sweeping efficiency. Use the storage stands to
support the weight of the broom head.
Operation
Always follow safety and operating information in this manual.
Always follow all safety and operating instructions of the loader.
Never remove material deflectors or warning labels.
Never operateAngle Broom unless you have been properly trained.
Make sure all safety labels are in place, look in this manual for their
locations.
Do not sweep toward people, buildings, etc. that may be injured or damaged
by flying debris.
Always relieve pressure before connecting ordisconnecting hydraulichoses.
Clean any debris from attachment. Pay special attention to any debris in
quick-tach area.
The angle broom is designedto be operated so that the brush sweeps debris
away from the operator (brush spins clockwise when looking from the motor
end). The brush will spin in the opposite direction, but has limited power
when in contact with the ground.
Sweeping Recommendations
Sweep with the wind whenever possible to provide more efficient operation
and keep debris off of the operator.
When sweeping on rough terrain, reduce machine ground speed to minimize
“bouncing”of broom head.
Debris direction can be controlled by angling the broom head.
Avoid excessive down pressure on the broom head. Brooms sweep with
the tips of the wafers; therefore, the sweeping contact pattern should be
about 2”-4”. Unnecessary down pressure promotes excessive wear and
premature failure of wafers. The weight of the broom head should provide
adequate down pressure for sweeping.

Sweeping Recommendations (continued)
When sweeping snow, increase brush speed and decrease travel speed.
This allows the snow to be removed effectively. In heavy or deep snow, use
multiple passes to clear the snow.
Use of the optional deflector will limit distance swept material is thrown.
Manual Angle Operation
Manual angle operation is achieved with a hitch pin located on the centering
swing linkage. Angles that are available are straight, 27° right or 27° left.
To change the angle of the brush head, lift broom head off of the ground,
remove the pin, swing the head in the desired direction and reinstall pin.
Make sure broom is not rotating and machine is shut off when changing the
angle manually.
Optional Hydraulic Angle with Electric Control Operation
If the machine has the electrical package (usually 8 or 14 pin connector for
skid loaders), connect the electrical plug to the plug on the boom arm of the
loader when hooking up the attachment to the loader. The angle of the
broom should now be controlled by primary electrical switch located in the
operator station of the machine.
If the machine does not have an electrical package, there are 2 options to
make the HydraulicAngle with Electric Controls work. If the machine has a
12 volt accessory plug (cigarette lighter), you can use the optional control
box for power. If the machine does not have a 12 volt accessory plug, a 12
volt accessory outlet is available from Virnig Manufacturing to connect to the
battery of the machine and then utilizes the optional control box.
In either of the above scenarios, the broom needs to be running in the
sweeping direction before the electro-hydraulic angle will function. The
hydraulic angle will not work if the broom is running in reverse.

Maintenance
*Before each use and after every 10 hours of operation
Grease hinge pins, linkage pins and bearing (8 fittings on Manual Angle, 10
fittings on Hydraulic Angle with Electric Control).
Check for wear on wafers. If the outside diameter of the wafers is one half
of the original diameter, the wafers need to be replaced. The original
diameter of the wafers for the Angle Broom is 32”.
Make sure all safety labels are in place, look in this manual for locations.
Check for loose, worn, or missing parts, repair or replace as needed.
Remove any foreign debris such as string, wire, etc. that may have wrapped
around the brush head.
Inspect motor, valve, hydraulic fittings, and hoses for leaks and damage.
Replace as needed. Make sure machine is shut off and hydraulic pressure
is relieved before checking for leaks. Never use hands to check for high
pressure hydraulic leaks.
The pressure relief valves require no maintenance. The valves are pre-set
and require no adjustment. Changing settings may cause damage to the
motor. Pleasecall Virnig Mfg. Inc. with anyquestions orproblems regarding
the pressure relief valves.
Contact your dealer for any required replacement parts.

Brush Replacement Procedure
Remove the 4 nuts (Item #1, see “Angle Broom Core Installation”section)
holding the Hydraulic Motor Assembly (Item #28) and remove the Hydraulic
Motor Assembly.
Remove the 4 nuts (Item #1, see “Angle Broom Core Installation”section)
holding the Angle Broom Shaft Assembly (Item #29) and remove the Angle
Broom Shaft Assembly.
The core should be free from the brush head. Lift brush head and remove
to expose core.
Remove the retaining plate from one end of the core (See “Core Assembly”
section).
Remove old brush sections. Inspect drive bars for indentations or
excessive wear. Replace core cage if damage is evident.
Stand core on end with retaining plate still attached and install the new brush
sections makingsure thedrive pinsof the wafer engage oneof thecore drive
bars. For a snug fit, install consecutive wafers so that the drive pins are
180° apart.
Reinstall the retaining plate and lay core on ground. When handling the
core, do not use the wafers to move the core.
Lower brush head over core with new brush sections.
Reinstall Angle Broom Shaft Assembly into core and secure with nuts.
Before reinstalling motor, remove the 3/8” bolt (Item #1, see “Angle Broom
Hydraulic Motor Assembly”section) holding the Drive Adapter (Item 38) on
the Hydraulic Motor (Item #7) and apply a thin layer of grease to the splines
of the motor. Reinstall Drive Adapter to the Hydraulic Motor.
Reinstall Hydraulic Motor Assembly and secure with nuts.
