Ⅰ. Safety
*Dangerous operations presented below are prohibited for safe use of this equipment.
*Dangerous operations can arouse serious damaging or failure of the equipment.
1. Basic Precautions
Check and gain full knowledge of safety labels in this Manual and on the equipment. Forest
equipment must be maintained in standard state at all times, and no alteration is allowed. If
safety is not secured, operational performance and durability of the equipment will gradually
decrease. Pay particular attention to safety over any other contents presented in this Manual.
Prohibition of remodeling
Remodeling the equipment without discussing with our company can cause serious safety risks,
and the equipment owner is responsible. Please discuss with our company if you would like to
remodel the equipment.
Safe clothing
Appropriate safety clothing such as helmet are required during work. Inappropriate attire and
accessories can induce unintended operation of the lever or other operating units. If the operator
loses focus, a serious accident can occur. To keep safety, prohibit the use of radio or headphone.
Caution for attachments
Make sure to contact our company before attaching special attachments to the equipment. Do
not use attachments that have not been approved by our company. We are not held responsible
for accidents and failures caused by the use of unapproved attachments.
Caution for handling oil
Oil is very dangerous because of flammability. Since there is a concern for ignition nearby
firearms, be extremely careful when handling oil. Keep the equipment clean by removing
foreign substance and grease. Do not pile up mops stained with oil as they can momentarily
show spontaneous ignition.

Prevention of burn
After stopping the equipment, conduct inspection and maintenance once temperature of the
equipment is cooled down. Be careful about getting burned by hot oil. Gear oil, operating oil,
high pressure hose and other pipe parts reach high temperature during operation.
Preparation of firefighting system
Be prepared for emergency injury or fire. Always keep first-aid kits and fire extinguisher ready.
In particular, be aware of how to use the fire extinguisher. Keep a memo on emergency contact
information such as phone numbers of hospitals, ambulances and fire stations.
Injury from attach and working devices
Be careful about rolling of hands, feet and body parts into operating parts such as between the
equipment and working devices, working devices and cylinder, etc. Narrowing of distance by
operation of operating devices can lead to serious human accidents.
Operation with window closed
During operation of the equipment, persons other than the operator must escape from the scope
of scattered and fallen objects that can occur during work.
Securing workplace safety
Check risk factors in the workplace before work. Decide the safest work method after
confirming the work environment.
Communication
Inaccurate communication can cause accidents. When working in groups, make sure that
workers understand hand signals of one another.

Fire prevention
Remove inflammable substances nearby the equipment. Inspect status of hydraulic pipes and
leaking of operating oil, and perform maintenance and repair as necessary. Leakage of
inflammable liquids such as fuel, lubricant and operating oil can cause fire. Inspect short circuit
and damaging of electric wiring that cause spark, and keep connecting parts of power cables
clean. Paint on the equipment surface must be removed before welding or heating. Do not apply
forcible heat on the hydraulic device or pipes. Confirm location and method of using the fire
extinguisher.
Prevention of collision of attachments
Check appropriate interval with the equipment in the case of a workplace with height limitation.
Caution for collision between attachments and operating room
Securing visibility
When working in a dark place, install additional working light as necessary.

Precaution for inspection and maintenance of hydraulic parts
Stop the equipment on a flat and solid ground surface. Put attachments down on the ground and
stop the engine. Do not perform maintenance immediately after work. Wait until the entire
equipment is completely cooled down. If the equipment is still hot and hydraulic parts have
residual pressure, the user can be seriously injured by spurting of hot operating oil. Residual
pressure inside the operating oil tank must be removed before performing maintenance on
hydraulic parts. Operate the working lever in the operating room many times to remove pressure
remaining in the hydraulic circuit. Keep body parts and face away from the workpiece when
loosening plugs and screws on the hydraulic line.
Warning sign during inspection and maintenance
To prevent persons other than the maintenance worker from moving the equipment during
inspection or maintenance, hang a warning sign for “Under maintenance” or “Inspection in
process” in the operating room or on the work lever.
Use appropriate tools.
Stop the engine to conduct inspection or maintenance on the equipment.
Keep the equipment clean.
Water can cause malfunctioning of electric devices.
Do not touch moving parts of the equipment with hands.
Be careful about high pressure of operating oil in the hydraulic circuit.

2. Dangerous Operations
The work methods introduced below are not permitted for the safe use of the equipment. Such
operations can cause serious damaging and failure of your equipment.
Do not work over the permitted scope of work.
Do not operate the equipment beyond its limit. Working beyond the limit can damage the
equipment and result in danger.
Do not lift the equipment using the wood grapple.
Do not strike or press the ground with the boom cylinder or wood grapple.

Do not rotate the body using the grapple.
Do not rotate the body using the boom cylinder or wood grapple.
Do not move the grapple above people.
Do not move the wood grapple above people’s head or
truck operating room. Direct collision with the wood
grapple or dropping of workpiece can lead to serious
injury or damaging of truck.
Do not perform hammering.
Do not use the grapple like a hammer or pile driver.
Striking solid ground or flattening the workplace floor
can seriously damage the wood grapple and boom.

HX260FC T3

Do not rotate the wood grapple when it is touching the ground surface.
Doing so can seriously damage the wood grapple, arm and connector.
Do not operate hastily.
Hasty operation can cause overturn of the equipment. Be careful to maintain stability of the
equipment.

HX260FC T3
