REMARK
• Use the L.H. brake pedal when operating the work equip-
ment while accelerating and decelerating the machine by
using the brake and accelerator. In this way, you can re-
strain the brake heating.
• When depressing the L.H. brake pedal, the modulation
clutch slips, and the temperature will increase due to the
friction.
Modulation clutch temperature caution lamp may light up if
the operation is continued under the following state.
• When the accelerator pedal is kept depressed
• When the engine speed is kept increased by the RPM
setting
• When the L.H. brake pedal is kept depressed to stop
the machine
• When the operation is continued with the L.H. brake
pedal kept slightly depressed (approximately 3 ° or
more)
The centralized warning lamp lights up, and the alarm buz-
zer sounds intermittently if such an operation is further per-
formed. Stop the machine, and run the engine at a medi-
um speed with no load until the caution lamp goes out.
ACCELERATOR PEDAL
The accelerator pedal is used to adjust the speed and output of
the engine.
It steplessly controls the engine from low idle to high idle.

lamp on the machine monitor is not lit, the work equipment lock is released and the work equipment can
