W0095A
The attachment quick coupler system and coupler bucket will give your machine increased versatility and function.
The ease of coupling, combined with a remote locking control allows for a single operator to handle the attachment
coupling and uncoupling operation without special tools and without leaving the cab.
DO NOT operate or permit anyone to operate or service the machine and/or attachments until you or the other per-
sons have read and understood the safety, operation and maintenance instructions in this manual. Use only trained
operators who have demonstrated the ability to operate the machine correctly and safely. The wheel loader with the
attachment quick coupler system and bucket is intended to be used for digging and general earth moving purposes
such as land leveling, truck loading, and material rehandling.
Safety precautions specific to attachment and coupler
• Always inspect the coupler locking pin extension be-
fore operating the machine. Position the locking pins in
your field of vision, and make certain they are engaged
properly.
• Improperly locked attachments may release and could
result in death or serious injury.
• Do not attempt to engage the attachment with the lock-
ing pins extended.
• Make certain that the locking pins and connections are
free of dirt or mud before attempting to engage and
disengage the attachment.
• Do not extend or retract the coupler locking pins with
the attachment on the ground or in the dump position.
• If any damage is visible on the coupler or attachment
points, do not operate or attach the bucket.
• Never stand under an attachment or allow others to do
so. Do not allow anyone under elevated loads.
• Do not lift loads or push materials with the coupler with-
out an attachment. This can cause damage to the cou-
pler components.
• Check coupler operation periodically for any unusual
movement and/or noise.
• Inspect hydraulic hoses for any leaks or damage.
• Visually inspect welds and make any repairs as neces-
sary.
• Check for any loose bolts. Torque as required.
• Do not modify the machine or attachments. Such mod-
ifications can damage and/or affect the integrity of the
attachment and can also affect safety and function of
the attachment and/or machine.
• Check all controls in a clear area and make certain the
machine is operating correctly.
