INTRODUCTION
This operang manual is an essenal tool to ensure the proper and safe operaon of the ES-34R Electric Rotary Mower. This user manual
contains important informaon regarding the safe, proper and ecient operaon of the ES-34R. Adherence to this manual will help to
avoid risk, lower repair costs and reduce downmes while simultaneously increasing the service life of the ES-34R itself. The operang
manual must always be available, and every person tasked with working on or with the ES-34R must read and follow the instrucons.
In the case of any diculty, or if further informaon or advice is required, our Service Department is always at your call. In the interests of
speed and accuracy of informaon please quote the serial numbers of the machine when making enquiries. For the machine, this is to be

MACHINE DESCRIPTION
A rotary cung machine manufactured with 34” (86cm) cung width this machine is run by a pair of 48V high eciency brushless
permanent magnet AC motors powered from an 111 Ah lithium ion baery.
The rear roller and cuer are controlled independently via belt drives operated from the display screen on the upper handle bar. A
mechanical parking brake is ed for added safety when working around uneven ground, when applied this disengages drive to both
motors for added safety.
In the design of the machine, special aenon has been given to the importance of easy service and maintenance with the construcon
based on a seconal assembly system. These are the Electrical Drive system, the Rear Roller Unit and the Front Roller Unit, each of which
can be readily removed individually from the main Frame Chassis Unit.

ES-34R MOWER BASIC CONTROLS
MECHANICAL PARKING BRAKE
• The machine has a mechanical parking brake located
on the side guard to be used when the machine is
not in use.
• This applies a mechanical brake to the rear roller. It is
only to be engaged when the machine is staonary, it
is NOT to stop the machine.
• Latch the brake lever below the brake boss to engage
and swing back above the brake boss to disengage
(TECHNICAL DATA, ITEM 11).
• The display will automacally display PARK on the
gear selecon icon when the brake is engaged.
• The brake must be disengaged before the gear
selecon can be changed by the operator.
NOTE:-
The mechanical parking brake is
engaged. This must be disengaged
to allow the mower display to be set
to drive or reverse.
NOTE:-
Pushing the mower, when not motor
driven, should always be done in
NEUTRAL to avoid damaging the
internal motor brake.
FOR THE LOCATION OF CONTROLS AND COMPONENTS REFER TO ‘TECHNICAL DATA’ PAGES. BE FAMILIAR WITH THE CONTROLS AND
THE PROPER USE OF THE EQUIPMENT BEFORE STARTING.
SWITCHING THE MOWER ON/OFF
• Ensure the EMERGENCY STOP buon is released before switching the mower on. It will not start otherwise.
• The KEY SWITCH controls power to the electrical components and can be used to switch the machine ON.
• To turn the mower OFF, turn the KEY SWITCH to the OFF posion or hit the EMERGENCY STOP buon.
MOVING OFF/STOPPING
• The DEADMANS HANDLE is an operator presence control. This must be depressed before the drivemotor will
engage. Releasing the handle during operaon will cut power to both motors.
• To drive, depress the DEADMANS HANDLE and then move the MOMENTARY LEVER. The machine will go into Drive
automacally and move forward. When the lever is moved to the le, the machine will return to Neutral when

• To reverse, select reverse on the display and then depress the DEADMANS HANDLE, and then THROTTLE. In
reverse, the machine will not return to Neutral.
CYLINDER OFF/ON
• The DEADMANS HANDLE is an operator presence control. This must be depressed before the deck motor will
engage. Releasing the handle during operaon will cut power to both motors.
• Press the CYLINDER ON/OFF buon on the display to acvate the cylinder.
• The cylinder will spin up to the set speed immediately
• When the DEADMANS HANDLE is released, the cylinder drive will disengage. It will not re-engage unl the
CYLINDER ON/OFF bu0n is pressed again.
• The motor will not engage while the machine is in reverse or neutral.
• The machine can also be controlled using the integrated display screen buons.

ES-34R HEIGHT OF CUT ADJUSTMENT
A
B
A
B
SETTING FOR HEIGHT OF CUT
Always stop the engine before adjusting the height of cut. Failure to do this may result in serious injury. The
length of grass after cutting depends on the height of the deck in relation to the ground.
To set:
●Turn Hand knob on top deck (View A) to raise and lower deck height.
●Use calibrated depth guage (View B) to measure height of deck.
Remember height of cut is a󰀨ected by moisture of turf, weight of machine and the thatch density. Di󰀨erent makes
of machine cut at di󰀨erent heights. We suggest you set it to a couple of mm above your planned height and then
come down in height by trial.
