OPERATION
The machine is designed for CUTTING and RECOVERY of ferrous materials.
The equipment can rotate to achieve the correct cutting angle.
During operation the operator must stay on board the excavator, in the position recommended by the
manufacturer.
No-one must stand with in a 30 m (100 ft) range of the excavator when it is working.
During installation and removal of the attachment, only the mechanic should be within 100 ft (30m) of the
operation .
Use the shear only as intended, in approved applications, as set forth in this manual. Do not allow shear,
exposed cylinder rod or hoses to come into contact with any obstacles, buildings, or the excavator.
The shear is not intended to crush or break objects or structures by swinging or dropping the shear.
START UP
During initial operation and any time jaw maintenance has been performed, process thin and lighter material
first to “work harden” wear areas, developing a harder, more durable edge. This is also the most effective
time to process materials such as sheet metal or wire. The new or repaired edges will cut more efficiently
and be less likely to get material jammed between the blades.
When operating in temperatures below freezing, it is also important to process light materials first.
This allows the shear’s structural material to “warm up,” preventing thermal cracking.
EFFICIENT AND PRODUCTIVE OPERATION
Operators should become accustomed to performing work in the most profitable manner possible.
When cutting, build up and cut out of small piles, keeping the surfaces of the shear chin plate and upper
jaw out of the dirt as much as possible. Dirt is much more abrasive than steel and needlessly increases
build-up and hard surfacing time and intervals.
It also helps to give yourself enough room to keep out of the way of other personnel and machines.
Material should be picked from a pile and swung to the side and cut in a new area. This prevents redundant
cutting of the same pieces and allows for the newly prepared material to be loaded out with another material
handling machine.
Material processing areas should be as close as safely possible to the location for loading materials for
transportation. Less time spent processing, loading and transporting materials greatly affects operational
costs and productivity and dramatically reduces man hours, fuel costs and wear on
equipment.
