Throttle Dial This rotary control provides progressive engine speed control over the full range.

Note: If the engine speed does not change even after turning the throttle dial it is because the idle switch (6) is ON. Push the idle switch to OFF to re activate the throttle dial.

This key operated rotary switch has four positions. The key can only be inserted or removed in the OFF position. The positions are: OFF - Isolates all electrics.

Turning key to this position stops the engine and, if appropriate, silences the warning buzzer.

HEAT: For pre-heating the engine air intake during cold weather, key must be held in this position.

Returns to OFF when key is released.

4

If the engine is started with the throttle dial not at the minimum position, no engine speed control will be possible until after the dial has been turned to the minimum position.

3

Hammer switch (if fitted)

ON - Switch position for normal running.

START: Key held in this position cranks the starter motor for starting the engine. Release the key when the engine starts and the switch returns to ON.

Boom Priority Switch-if fitted (Standard on JS330)

Pressing this switch instantly changes the engine rpm back and forth between that selected for working and a ‘low idling’ speed. When ‘low idling’ has been selected the message “LOW IDLE” is displayed on the Display Monitor. This facility is overridden when the Manual/Auto Change switch is set to ‘Auto’.

Press the switch to change priority of boom raise to swing. Selecting the boom priority switch during simultaneous slew and boom operation will restrict flow to the slew motor and therefore give more flow to the boom up operation.

When the switch is pressed the monitor will display “BOOM PRIOR” acknowledgement message.

5

Power-up Button With the Work Mode Selection switch in ‘H’ or ‘S’ mode, depression of the button initiates the application of maximum digging power for a period of 8 seconds, during which time the ‘POWER UP’ message is displayed on the Display Monitor.

One Touch Idle Switch

7

Auxiliary Circuit Switch This three-position rocker switch, spring loaded to the central OFF position, provides bi-directional flow for relevant attachments, e.g. weedcutter, grab rotate.

Press and hold the switch to the right or left, as appropriate, for as long as the attachment is to be used. Release the switch to turn off the attachment.

Lightswitch Panel Work Light Switch Press the switch A to the first position to switch ON the Standard work lights (on boom and the right hand of the machine). Press the switch to the second position to switch ON the optional lights (on the cab and the counterweight - if fitted).
