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 the motor provide hydraulic
protection 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
lb.
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 hydraulics.
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 (cont.)
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 store Angle 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 operate Angle 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 or disconnecting hydraulic
hoses.
Clean any debris from attachment. Pay special attention to any debris
in quick-tach area.
The angle broom is designed to 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 (cont.)
Whensweeping 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 (7 pin, 8 pin 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 Hydraulic Angle 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. Please call Virnig Mfg. Inc. with any questions or
problems 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 Hydraulic Motor
Assembly”section) holding the Hydraulic Motor Assembly and remove
the Hydraulic Motor Assembly.
Remove the 4 nuts (Item #1, see “Angle Broom Core and Shaft
Assembly”section) holding the Angle Broom Shaft Assembly 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 “Angle Broom
Core and Shaft 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 making sure the drive pins of the wafer engage one of the
core 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 #45, see “Angle
Broom Hydraulic Motor Assembly”section) holding the Drive Adapter
(Item #48) on the Hydraulic Motor (Item #47) 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.
