For CAT®** Mini Excavators and Backhoe LoadersMANUAL MINI COUPLER

The JRB Manual Mini Couplers, by Paladin, provide increased flexibility to operate multiple attachments on a single excavator or backhoe loader.

• Easily allows operator to change attachments and gain back lost productivity from knocking out pins

• Attachment changes are faster and safer • Spring loaded locking mechanism with integrated

non-removable locking pin

• Works in both backhoe and face positions

• Clear visibility of locking mechanism aids secure attachment

• Cast Manual couplers for 1-5 ton mini-excavators, backhoe loader coupler (CAT only)

Manual Mini Coupler Features

• Strong, lightweight cast design minimizes effect on machine performance

• Manufactured with a process utilizing high grade steel to produce a lighter, stronger and more durable design

• Cast design provides additional strength in the specific areas that require it, while minimizing weight in areas that are not load bearing

• The lighter weight improves machine efficiency and reduces fuel consumption

• Can be welded if necessary

• The base of the hook is flat to stop engagement of the attachment from the operators cab, forcing operator to install the locking pin as part of future ISO13031 regulation

Coupler Operating Handle

For CAT®** Mini Excavators and Backhoe Loaders

Step 1: Remove lynch pin and slide locking pin out to the hook release position. Lower the coupler and engage front bucket pin.

Step 2: Lift the bucket slightly off the ground. Rotate bucket towards cab until the back bucket pin bears against the hook. Insert the coupler operating handle into the hole at the back of the coupler.

Step 3: Press down on the coupler operating handle to open the hook. The weight of the bucket drives the back bucket pin into the back socket of the coupler. Engage the hook by taking pressure off the coupler operating handle. Remove the coupler operating handle.

Step 4: Slide the non-removable locking pin into the coupler and secure in place using the lynch pin (see insert)

Step 5: Check that the bucket pins are securely held by the coupler. Apply pressure to the bucket by rotating it against the ground and away from the machine.

Step 1: Raise the bucket slightly off the ground and slightly angle bucket teeth towards the ground - this will allow the bucket to rotate away from the rear pin after the coupler operating handle has released the hook. Remove the lynch pin which secures the non-removable locking pin. Slide the locking pin out to the hook release position.

Step 2: Insert the coupler operating handle into the hole at the back of the coupler.

Step 3: Press down on the coupler operating handle to disengage the hook and release the rear bucket pin. The bucket will swing forward on the front bucket pin. Caution: the bucket is now engaged by the front pin only and may fall. Remove the coupler operating handle.

Step 4: Lower bucket to the ground. Rotate coupler away from the cab to release the front bucket pin.
