If installing 2nd attachment line as a field kit, ask distributor to change monitor setting to allow 2 attachments.
The switch on left lever is a roller proportional control switch. Rolling the switch up produces rotation in one di-
rection, rolling down produces rotation in the opposite direction. Slight movement of the roller will give slight
movement of the attachment; full movement of the roller will give faster movement of the attachment.
If the working mode pilot monitor does not display ATT/P or
ATT/E for the attachment mode, follow the instructions, see
"WHEN USING GENERAL
CRUSHER"

MAINTENANCE OF ADDITIONAL FILTER FOR BREAKER

• Immediately after the engine is stopped, its parts and oil are still very hot, and may cause burn in-
jury. Accordingly, wait until they have cooled down before starting the work.
• When using compressed air, there is a danger that dirt may scatter and cause personal injury.
Always wear protective equipment such as protective eyeglasses and dust mask.
