SAFETY INFORMATION
TO THE OPERATOR
It is the responsibility of all operators to read and understand this entire manual before installing, operating or
servicing the PREMIER Ammbusher Brush Cutter. Pay particular attention to cautions, warnings and safe operating
procedures. Be a safe and qualified operator. Operate your equipment with care and good judgment and see to it
that it is properly maintained.
SAFETY DECALS
WORN, DAMAGED OR ILLEGIBLE SAFETY DECALS MUST BE REPLACED. New safety decals can be ordered
from Premier. Safety decals for Premier Ammbusher Brush Cutters are ordered and packaged in sets only.
SAFETY INSTRUCTIONS
DISCHARGE DANGER LABEL
The PREMIER Brush Cutter discharges materials out the front. When cutting
with the PREMIER Brush Cutter, never discharge material toward bystanders
nor allow anyone near the machine while in operation.
When cutting near bystanders is unavoidable, do not operate the cutter without Front
Deflector Chains in place, and do not cut in the direction of bystanders. Bystanders
must be at least 75 ft (23M) away when operating.
Clear the work area of objects (fencing, rocks, bottles, wire, etc.) which might be
picked up and thrown.
Always use a shatterproof cab door for your loader or the 3/8” thick safety door when
cutting brush. This is not only to protect you from thrown objects, but primarily to
prevent overhanging or protruding objects such as rebar, tree limbs, or other objects
from entering the cab and causing operator injury.
Disengage power to the PREMIER Brush Cutter and shut the loader engine OFF
before leaving the operators cab.
Shut the PREMIER Brush Cutter down and the loader engine OFF before performing
any inspection or maintenance to the cutter.
NEVER place hands or feet under the Brush Cutter deck or near any moving parts when
unit is running. Always keep clear of front discharge area when operating Brush Cutter.
CAUTION LABEL
If this label is on your machine, it means your machine is not equipped to
operate with hi-flow loaders. Use on hi-flow loaders will cause premature
motor failure. PREMIER is not responsible for damage incurred to the
hydraulic motor due to hi-flow usage.
HYDRAULIC LEAK WARNING LABEL
The PREMIER Ammbusher Brush Cutter has been designed to reduce the
likelihood of hydraulic system leakage. Each Brush Cutter’s hydraulic system
is tested and inspected prior to shipping. However, over time, any hydraulic
system may develop fluid leaks, and very small leaks may produce high-
pressure discharge flows capable of causing injury should skin come in
contact with such discharge.
6

SAFETY INFORMATION
(continued)
Do not raise the back of the PREMIER Brush Cutter (nearest operator) over 2 feet off the ground. Never
expose yourself or a bystander to the rotating blades.
When driving the loader to and from the worksite, carry the PREMIER Brush Cutter as low as possible to the
ground to avoid the possibility of tipping forward.
Do not carry passengers on the PREMIER Brush Cutter.
Never leave the PREMIER Brush Cutter unattended in a raised position.
The loader and PREMIER Brush Cutter should be stopped and inspected for damage after striking a foreign
object, and the damage should be repaired before restarting and continuing cutting.
Cut only in daylight or good artificial light.
Keep all nuts, bolts and screws tight, and be sure the equipment is in a safe working condition.
Check the blade mounting bolts for proper tightness at frequent intervals.
When working under the PREMIER Brush Cutter, always securely block it up. If attached to your loader,
visually inspect your lock-on pins to make sure the Brush Cutter is locked onto your loader. Remember, the
PREMIER Ammbusher Brush Cutter weighs more than 1600 lbs.
Reduce speed on slopes and make turns gradually to prevent tipping or loss of control. Exercise caution
when changing direction on slopes.
Stay alert for drop-offs or holes in the terrain.
Use caution when walking on the Brush Cutter deck. The deck can be slick when wet.
Never drive your skid loader with your PREMIER Brush Cutter raised more than 2 feet. Children are small.
Be aware of their presence and ALWAYS make sure you can see what you are cutting.

HOOK-UP PROCEDURES
NOTE: BECAUSE OF THE DIFFERENCES IN ATTACHMENT MOUNTING METHODS AMONG THE VARIOUS
BRANDS OF SKID STEER LOADERS, IT IS IMPORTANT TO CONSULT YOUR SKID STEER OWNERS
MANUAL FOR THE PROPER ATTACHMENT MOUNTING METHOD.
1. Pull up and connect the Brush Cutter to your loader.
2. Secure locking levers. NOTE: Do not attempt to operate attachments with damaged or disengaged lock pins.
3. Connect (2) hydraulic hoses.
TO REMOVE BRUSH CUTTER ATTACHMENT
NOTE: BECAUSE OF THE DIFFERENCES IN ATTACHMENT MOUNTING AND REMOVAL METHODS
AMONG THE VARIOUS BRANDS OF SKID STEERS, IT IS IMPORTANT TO CONSULT YOUR SKID STEER
OWNERS MANUAL FOR THE PROPER ATTACHMENT REMOVAL METHOD.
1. Lower the PREMIER Brush Cutter to ground level.
2. Stop the engine, release hydraulic pressure in hoses and disconnect auxiliary hoses.
3. Release the locking levers and disengage the loader mounting plate.
OPERATING INSTRUCTIONS
The PREMIER Ammbusher Brush Cutter is capable of cutting trees and vegetation of varying height up to 7” in
diameter. Designed to make your loader more versatile, the PREMIER Ammbusher Brush Cutter is intended to
perform these functions without the front of the mower deck being raised to a vertical height greater than 3
feet.
As an additional safety feature, the PREMIER Ammbusher Brush Cutter is designed with a front-edge chain
curtain. This is provided to reduce the likelihood of discharged objects. Always use a safety door on the front of
your loader to provide the operator an additional level of protection from both overhanging objects (such as tree
limbs) and the potential of discharged objects.
1. Start the Brush cutter with the loader running slightly above idle. Engage the loader hydraulics and gradually
throttle up to the desired RPM. Maintaining a constant RPM, along with a slower travel speed, will increase your
cutting efficiency.
2. Raise the back of the Brush Cutter (nearest the operator) 4 or 5 inches off the ground. This is necessary for
material to clear from under the cutting deck. Rotate the Brush Cutter front up or down so that the skid rails
are 1 - 2 inches off the ground. The Brush Cutter deck will be sloping front-down (away) from the operator.
This is the optimum method for cutting close to the ground.
Never drive your loader with the Brush Cutter raised more than 2 feet or tilted to the point that your
view is obstructed. Always make sure you can see what you are cutting.
Never operate the Brush Cutter in populated areas, or where thrown objects could injure persons or
damage property. Safety chains MUST be installed.
Never raise the back of the Brush Cutter more than 2 feet off the ground. Never expose yourself or anyone else
to the rotating blades. If you can see the rotating blades when operating the unit, the back of the Brush Cutter
is raised too high.
3. When cutting large brush, operate the PREMIER Ammbusher Brush Cutter in the following manner:
Slowly drive into the tree and allow the front spring door to open up as you bend the tree with the push bar.
This allows the blades to cut the tree off. The tree can now be mulched by rotating the front up, driving forward
several feet, rolling the front down onto the tree and back-dragging. Keep in mind that, although you can cut
larger trees, the operational life of the attachment may be shortened.

REPAIR AND MAINTENANCE
PART “A”
BLADE CARRIER REMOVAL
This operation should be performed by an authorized dealer or qualified technician. The blade carrier
weighs approximately 250 pounds. Should it unexpectedly shift during removal, it could result in
personal injury. An overhead hoist with the appropriate lifting capacity is recommended for this
operation.
1. Set the Brush Cutter flat on the ground. Turn the skid loader engine off to disconnect the hydraulic
hoses from the loader. Then, safely disconnect the Brush Cutter from the loader.
2. Attach the hoist to the two lifting points on the push bar.
3. Lift the front of the Brush Cutter, allowing it to lay back upside down, while blocking and bracing the rear
of the Brush Cutter to protect the motor cover and hydraulics.
4. Block the Brush Cutter to ensure that it is stable.
5. Attach the hoist to two opposite arms on the blade carrier and apply very light tension. This is a safety
precaution to be taken before removing the cap screws.
6. Remove the (8) cap screws and (8) washers that secure the blade carrier to the drive flange, and lift the
blade carrier with the hoist.
PART “B”
