Attachments And Buckets
NOTE:Warranty is void if non–approved attachments are used on the Bobcat loader.
Never use attachments or buckets which are not approved by Bobcat Company. Buckets and attachments for safe loads of specified densities are approved for each model. Unapproved attachments can cause injury or death.
W–2052–1285
The dealer can identify, for each model loader, the attachments and buckets approved by BobcatCompany. The buckets and attachments are approved for rated operating capacity and for secure fastening to the Bob–Tach.
The rated operating capacity for this loader is shown on a decal in the operator cab. (See SPECIFICATIONS Page 93 ) The rated operating capacity is determined by using a standard dirt bucket, and material of normal density, such as dirt or dry gravel. If longer buckets are used, the load center moves forward and reduces the rated operating capacity. If very dense material is loaded, the volume must be reduced.
Exceeding the rated operatingcapacity [A] can cause the following problems:
1.Steering the loader may be difficult.
2.Tires will wear faster.
3.There will be a loss of stability.
4.The life of the Bobcat loader will be reduced. Use the correct size bucket for the type and density of material being handled. For safe handling of materials and avoiding machine damage, the attachment (or bucket) should handle a full load without going over the rated operating capacity for the loader. Partial loads make steering more difficult.
Maximum load to be carried when using a pallet fork are shown in figure [B]. See your Bobcat loader dealer for more information about pallet forks and other available attachments.
Do not exceed rated operating capacity. Excessive load can cause tipping or loss of control.

The levers will contact the frame as shown (Item 1) [C] when locked.
If the levers do not engage in the locked position, see your Bobcat loader dealer for maintenance.
Bob–Tach levers have spring tension. Hold lever tightly and release slowly. Failure to obey warning can cause injury.
ATTACHMENTS AND BUCKETS (Cont’d)
The wedges (Item 1) [A] must extend through the holes (Item 1) [B] in the mounting frame of the bucket (or attachment), securely fastening the bucket to the Bob–Tach. The wedge is shown extending through the hole in the bucket [A]
Bob–Tach wedges must extend through the holes in attachment. Levers must be fully down and locked. Failure to secure wedges can allow attachment to come off and cause injury or death.
Removing The Bucket Or Attachment
Put the attachment flat on the ground and lower or close the hydraulic equipment. If the attachment is hydraulically controlled (ie: combination bucket, backhoe, etc.), stop the engine and relieve hydraulic pressure in the auxiliary circuit (See Relieving Hydraulic Pressure, Page 17).
Raise the seat bar, unfasten the seat belt, set theparking brake and exit the loader.
Pull the Bob–Tach levers [C] all the way up.
Disconnect the hydraulic hoses, if necessary. Enter the loader.
Fasten the seat belt, lower the seat bar, start the engine and press the green PRESS TO OPERATE Button.
Release the parking brake.
Lower the lift arms and tilt the Bob–Tach forward. Move the loader backward, away from the bucket or attachment [D]
Operating Procedure
When operating on a public road or highway, always follow local regulations. For example: Slow Moving Vehicle sign or direction signals may be required. Always warm the engine and hydrostatic system before operating the loader.
A WITH
Machines warmed up with moderate engine speed and light load have longer life.
Operate the loader with the engine at full speed for maximum horsepower. Move the steering levers only a small amount to operate the loader slowly.
New operators must operate the loader in an open area without bystanders. Operate the controls until the loader can be handled at an efficient and safe rate for all conditions of the work area.
With a full bucket, go up or downthe slope with the heavy end toward the top of the slope [A] & [B]
With empty bucket, go down or up the slope with the heavy end toward the top of the slope [C] & [D].
B
C
• Keep the lift arms as low as possible.
• Do not travel or turn with the lift arms up.
• Turn on level ground.
• Go up and down slopes, not across them.
• Keep the heavy end of the machine uphill.
• Do not overload the machine.
Failure to obey warnings can cause the machine to tip or roll over and cause injury or death.
Raise the bucket only high enough to avoid obstructions on rough ground.
