parts may lead to unit damage and/or injury to personnel. The machines warranty may be
voided if unauthorized parts and attachments are used.

Safety Precautions
1.2
OPERATING SAFETY
• Plan ahead and learn as much as possible about your job-site area before beginning any
work.
• Know the exact location of overhead power lines or obstructions.
• Have all buried lines such as gas, electric, water, telephone, and cable TV, marked by the
proper authorities.
• Prior to use, perform the “Pre-Start Inspection” and “Daily Maintenance” to make sure that
the unit is in safe operating condition.
• Never operate a malfunctioning unit!
• Keep hands, gloves, shoes, control knobs, and operator platform clean. Slippery controls
can cause you to lose control, which may result in an accident.
• Always keep a firm grip on the hand rails located at the operator’s platform during travel
and operation to prevent falling off the unit.
• When working on an unfamiliar construction site, review, understand, and follow job site
safety rules.
• Keep the work site clear of all non-operating personnel. Should a person enter the work
area, stop machine operation until the work area is clear.
• Prior to unloading the unit and starting to work, inspect the path you will travel and work
site area for potential hazards. Some of the hazardous conditions you may encounter are:
- Holes
- Deep ditches or excavations
- Drop-os
- Soft un-compacted soil
- Culverts
- Deep mud/Standing Water
- Large rocks
- Slippery surfaces
- Steep slopes
- Tall grass, trees or shrubs
If any of these conditions exist, correct the hazard or obstruction. If any of these conditions
can not be corrected, avoid operating or traveling near them.
• Be extremely cautious traveling through or near trees, brush, shrubs or any obstacles which
might obscure your vision. These might hide potential hazards, such as the edge of a steep
slope, deep holes, large rocks, etc.
• Never operate near a ditch or embankment where loose or soft ground conditions could
cause the surface to give way under the machine causing it to become unstable.
• Never exceed the rated capacity of the machine. When using attachments, know their
capacity ratings and unit limitations. Unit specifications can be found in the Operator’s
Manual.

Safety Precautions
1.3
• Never attempt to operate any attachment without first understanding proper installation
and operating procedures. The center of gravity, stability, and operating characteristics of
the entire machine will change with the use of different attachments.
• Operate all controls slowly and smoothly and never abruptly stop any function. This can
cause the machine to become unstable.
• Always look in the direction of travel.
• Come to a complete stop prior to reversing travel directions.
• Reduce speed and proceed with caution when traveling in reverse or turning.
• Never travel with the loader boom or attachment raised. Lower the boom or attachment as
soon as possible and travel with the boom at the lowest safe height.
• When traveling with a loaded bucket or forks, the load should be level and the bucket or
forks tilted back to reduce spilling or losing the load.
• Approach corners slowly, turning too fast or sharp may cause the machine to tip over.
• Stay alert when operating near traffic or roadways.
• If the unit should begin to tip or become unstable, DO NOT try to stabilize the unit with
your legs or arms.
• If the unit is involved in an accident or inadvertently damaged during operation, stop and
perform a thorough inspection. Make sure the unit is in safe operating condition prior to
resuming work.
• Be alert to any unusual reaction to any of the controls. If anything unusual is noticed, shut
the machine down and thoroughly inspect it to determine the cause of the problem. Do not
operate the machine until all required repairs have been made.
• If the unit must be left unattended, shut the machine down and make sure that it can not be
started by an unauthorized individual.
• Operating on steep slopes can be dangerous and there is a greater risk of the machine
tipping over or becoming unstable. The list of rules below must be understood and
followed for maximum safety:
- Avoid excessively steep slopes or unstable surfaces. If travel on a slope is
necessary, keep the load low and proceed with extreme caution.
- DO NOT travel ACROSS excessively steep slopes under any circustances.
- Travel straight up and down slopes with the heavy end of the machine
pointing up the incline. When the machine has no load, the operator’s platform end
of the machine is considered the heavy end. When the machine is loaded or has an
attachment on the front of the machine, the front is considered the heavy end.
- Turning on slopes is not a recommended practice, however if you must turn on slopes;
reduce travel speed to as slow as possible, and exercise extreme caution. Avoid sharp
turns or sudden movements.
- Wet or slick ground conditions should be avoided as reduced traction could cause the
machine to slide down the slope.
- Do not attempt to install or remove attachments on a slope.
- Never park the unit on a slope.

Safety Precautions
1.4
SERVICE & MAINTENANCE SAFETY
Maintenance work can be hazardous if not done in a careful manner. All personnel should
realize the hazards and strictly follow safe maintenance practices. Failure to comply with
these safety precautions may result in serious personal injury and/or death.
• Use only Morbark, LLC supplied or approved replacement parts and attachments.
Imitation parts may lead to unit damage and/or injury to personnel. Warranty may be
voided if unauthorized parts and attachments are used.
• Wear the proper protective clothing and personal safety equipment necessary to perform
the maintenance or service required.
• Keep the machine free of grass, leaves or other debris build-up.
• Clean up oil or fuel spillage.
Fuel, oil leaks or spills can create a re or explosion hazard.
• Prior to performing maintenance or service, park the unit in a level area away from
obstructions and/or work site hazards.
• Be sure the area has adequate light and is well ventilated. NEVER operate the machine
inside a closed area.
• Clean-up any oil, grease, mud, water or snow which might cause the floor surface to
become slippery.
• If the machine requires maintenance, take the machine out of service and attach a “Do Not
Operate” tag at the control panel and remove the ignition key.
• If maintenance or repairs require the boom to be raised, the “Hydraulic Cylinder Lock”
must be installed.
• Know where all pinch points and rotating parts on the unit are. These areas must be
avoided to prevent serious injury.
• Remove only those guards or covers on the component being serviced and replace them
immediately upon completion of the work.
• Never attempt to adjust or service engine or machine components while they are hot.
ELECTRICAL SYSTEM HAZARDS
• Prior to working on the electrical system:
- Disconnect battery cables, removing the battery ground cable rst.
- When re-connecting the battery, connect the battery ground cable last.
- Never allow battery cables to contact hydraulic lines or rub against sharp
edges.
WARNING

Safety Precautions
1.5
Battery Hazards
Before working with batteries, the following are important points about battery safety that
you should be aware of:
• Batteries are always surrounded by extremely explosive gases. This is especially true when
the battery is being charged. To avoid explosion:
- Do not smoke near batteries.
- Keep arcs, sparks, and open ames away from batteries.
- Perform battery service work only in a well ventilated area.
• Make sure to dispose of batteries according to local regulations.
• Electrolyte Hazards:
NOTE: The batteries on the machine may be either be “wet cell” or “gel cell”. It is still
important to know and follow these warnings and cautions.
Battery electrolyte in standard “wet cell” batteries contains sulfuric acid which is poisonous
and can cause severe chemical burns. To avoid personal injury:
- Wear a face shield to prevent sulfuric acid contact with your eyes.
- Wear chemical resistant gloves and clothing to keep acid o your skin and
clothing.
- Since wet cell batteries give o explosive gases, use a ashlight to check the electrolyte
level, not an open ame such as a match.
- Never check the battery by placing a metal object across the battery posts. The resulting
spark could ignite anything ammable, causing re or an explosion.
- If electrolyte is splashed into your eyes, ush them immediately with clean water and
seek medical attention.
- If electrolyte is swallowed, seek medical attention immediately.
- If electrolyte is splashed onto exposed skin or clothing, ush and clean the area
immediately with clean water and seek medical attention if necessary.
Jump Starting/Battery Charging Hazards
Follow the instructions for jump starting or battery charging in the engine owner’s manual.
You must be at the operator’s platform when attempting to start the unit with booster batteries
and jumper cables so that you are at the controls when the engine starts.
Here are some general safety rules you must follow for jump starting the machine:
• Make sure to connect the positive jumper cable to the positive (RED) remote starter lug on
the right side of the machine chassis.
• Connect the negative cable to the engine, machine chassis or the furthest ground point
away from the battery. Never make the final connection at the starter or dead battery.
Sparks may ignite the explosive gases surrounding the battery.
• When disconnecting cables after jump starting, remove the negative cable first and then the
positive cable. IMPORTANT: DO NOT let the cable clamps touch when disconnecting
them. Severe damage can occur to the booster battery or machine.
• Never charge a battery or attempt to jump start a frozen battery. The sudden surge in
electrical power could cause the battery to explode.

Safety Precautions
1.6
Hydraulic System Hazards
The hydraulic system is under pressure whenever the engine is running and may hold
pressure even after the engine is shut o. Cycle all hydraulic controls after the loader boom
is resting on the ground. Some components will retain residual or trapped pressure. Use
extreme caution when removing any hydraulic component.
During inspection of the hydraulic system:
• Cycle all hydraulic controls to release residual pressure.
• Wait for the hydraulic fluid to cool down before disconnecting any hydraulic lines. Hot
hydraulic fluid can cause severe burns.
Hydraulic oil under pressure can penetrate body tissue causing serious injury and
possible death. When troubleshooting a hydraulic system for leaks, always use
cardboard or wood as a detector. DO NOT USE YOUR BARE HANDS. If you are
injected with hydraulic oil or any other uids, immediately seek treatment by a doctor
trained in the treatment of penetrating uid injuries.
• Hydraulic fluid can cause permanent eye injury. Wear safety glasses or a full face shield to
provide appropriate eye protection.
• When venting or filling the hydraulic system, loosen the filler cap slowly to allow any
pressure in the hydraulic tank to be released and remove the cap gradually.
WARNING

Safety Precautions
1.7
Fueling Hazards
Most fuels are highly ammable. Observe the following precautionary practices to reduce the
possibility of a serious accident:
• Always refuel the unit in an open, well ventilated area away from sparks or open flames.
Gasoline Engines:
• Shut the engine o before attempting to fuel the machine. Never refuel a unit
while it is running.
• Allow engine to cool before re-fueling.
• Always use a funnel or pour spout when lling the tanks.
• Under certain circumstances a static charge can develop and ignite the fuel.
Make sure that you are standing on the ground when lling the fuel tanks.
• If you are lling the fuel tanks from a service vehicle, make sure to connect
the service vehicles ground cable to the machine before beginning the fueling
process. Keep the fuel nozzle in constant contact with the rim of the machines
fuel tank.
• When lling a portable gas container, always place it on the ground. Never ll
a portable fuel container while it is inside a vehicle, truck, pick-up bed or any
surface.
• To avoid static sparks when using a portable fuel container, only ll the
container when it is positioned on the ground and keep the fuel container nozzle
in contact with the tank opening during lling.
• Make sure to move the unit from the transport truck or trailer and only refuel
the unit on the ground, using an approved container.
• Keep sparks and ames away from fuel.
• Do not smoke while refueling or when handling the fuel container.
• Never cut or weld on or near fuel lines, tanks or containers.
• Never overll the tank.
• Clean up spilled fuel immediately.
• Store fuel in an approved container and keep out of the reach of children.

Safety Precautions
1.8
Boxer Brush/Sweeper Attachment Silica Dust Caution
An OSHA ruling has established new permissible exposure limits (PEL) for occupa-
tional exposure to respriable crystalline silica. OSHA standard 29 CFR 1926.1153
covers the construction industry, and 29 CFR 1910.1053 covers the general and
maritime industries. The rules also requires employee protections such as perform-
ing exposure assessments, using exposure control methods, using respiratory pro-
tections, offering medical surveillance, developing hazard communication informa-
tion, and keeping silica-related records.
Under the new standard the employer shall not allow dry sweeping or dry brushing
where such activity could contribute to employee exposure to respirable crystalline
silica unless wet sweeping, HEPA-ltered vacuuming or other methods that minimize
the likelihood of exposure are not feasible. The employer bears the burden of show-
ing the alternative methods are not feasible.
-The use of non-grit, oil, or waxed based sweeping compounds are an acceptable
dust suppression housekeeping method.
-The use of compressed air for cleaning is allowed where the compressed air is
used in conjunction with a ventilation system that effectively captures the dust cloud
created by the compressed air, or where no alternative method is feasible.
-The employer’s exposure control plan must include the description of the house-
keeping measures.
