Pay attention during operation
Do not read, do not listen to music, do not talk over the cell phone during the operation. Do not operate the
grab as well as the carrier carelessly.
1.4. Safety information for maintenance of the grab
Follow the manual
Follow the instructions described in the manual when performing
maintenance work on the grab. Pay your careful attention to all relevant
safety regulations. Do not hurry. Most of accidents occur when the
instructions are not observed.
Use proper tools
The proper tools should be used for the maintenance work. Use of
improper tools may cause personal injury or damage to the parts of the
grab. Wear the eye protective glasses especially when removing and
replacing the cutter blades because the metal chips may fly off and
cause injury if they are struck with a hand hammer made of steel.

Use only the lug provided and sufficiently powerful lifting equipment when lifting the grab. Lug and ropes
must be in good condition.
Ensure that the grab and carrier stop completely
Maintenance work should be performed with the grab completely closed. Make sure to shut-off the stop valve
of the hydraulic line for the grab or to use a support to sustain the opened grab if maintenance work should
be carried out with the grab opened.
Place the carrier on the firm and flat ground with all the control levers or switches in a safe position.
Pay attention to hot oil and high pressure in hydraulic system
Special attention is required when performing maintenance of hydraulic
system. Never disassemble the grab as soon as the grab has been
stopped because the hydraulic system is still in high pressure. Follow the
instructions and release the residual pressure in the system. Pressure
may remain in the speed up valve, and it may be burst if it is
disassembled with the pressure inside.
Oil running out from the crack or small hole on hydraulic system may
cause personal injury. The hydraulic oil becomes very hot. And
compressed air in the oil tank may cause oil spouting when
disconnecting the line. Bleed off the compressed air by opening slowly
the filer cap of the oil tank.
