Operation
Differences in Operation
The LineDriver ES operates differently than a gasoline
powered LineDriver.
1. LineDriver ES rolls freely, especially on inclines,
when the power is off. Set Parking/Emergency
Brake before turning off.
2. Turn power on before releasing Parking/Emergency
Brake.
3. Performance drops when the battery charge
becomes low. When there is about one hour of runtime remaining, the Voltage Meter begins to flash.
When the batteries are deeply discharged and the
LineDriver ES is about to shut down, the buzzer
sounds about once per second.
4. The response of the Direction/Speed pedals is
softer. Learn this softer response before operating
on a job site.
How to Operate
1. Sit on seat to actuate Seat Interlock Switch. Ensure
Direction/Speed Pedals are not depressed.
2. Turn Power Switch ON. Buzzer will sound in a few
seconds, indicating that the Direction/Speed Pedals
are now active.
3. Disengage Parking/Emergency Brake on LineDriver
and any brakes on attached equipment.
5. Push striper or grinder handle bars to begin desired
turn.
FREEWHEEL HAZARD
Turning the Power Switch OFF will result in loss of
drive power. Loss of drive power causes LineDriver to
freewheel, which allows it to roll freely.
• Do not turn Power Switch OFF while LineDriver is in
motion.
• If loss of drive power occurs while LineDriver is in
motion, use the Parking/Emergency Brake to bring
LineDriver to a stop.
• Always engage Parking/Emergency Brake before
turning Power Switch OFF or standing up from
seat.
6. Move Direction/Speed pedals to drive the LineDriver, as shown below. Switching from forward to
reverse creates a braking action.
NOTE: LineDriver stops when both feet are removed
from pedals.
4. Squeeze hand control to release caster wheel of
attached equipment.
NOTE: LineDriver motion is forward and reverse. Turns
are made with the striper or grinder.
3A6623D 9
Operation
7. Engage Parking/Emergency Brake when not operating LineDriver. This prevents rolling when on an
incline.
Operating on Inclines
Extended Braking Distance
Starting and Stopping on an Incline
1. Engage the Parking/Emergency Brake before turning the Power Switch to OFF when parking on an
incline.
2. Turn the Power Switch to ON, and allow the
machine to initialize before releasing the Parking/Emergency Brake when starting on an incline.
Trailer Loading & Unloading
NOTE: LineDriver ES rolls freely, especially on inclines,
when the power is off. Set Parking/Emergency Brake
before turning off. Turn power on before releasing Parking/Emergency Brake.
1. Always keep LineDriver connected to striper or
grinder.
2. Use a level surface to load and unload. Leave sufficient space behind ramps.
3. Use loading ramps of sufficient length and capable
of handling weight of unit and operator.
4. Adjust striper or grinder handlebar to highest position. Slide seat back as far as possible.
Operating on inclines results in extended braking distances.
1. Select Incline/ECO mode on Speed Switch when
operating on inclines.
2. Be prepared to use the Parking/Emergency Brake
when operating on inclines.
NOTE: Do not operate on inclines greater than 7.5
(13%).
REDUCED BRAKING HAZARD
The braking from the Direction/Speed pedals can be
significantly reduced when going down inclines at
speeds over 6.5 mph (10 kph). This reduced braking
results in longer braking distance than normal, which
could lead to an accident.
A continuous buzzer alarm will sound when this
reduced braking condition occurs. If this alarm
sounds, apply the Parking/Emergency Brake to slow
down. Failure to do so could result in serious injury.
• Do not drive in a manner that causes this alarm to
sound.
°
5. Use right foot to engage Parking/Emergency Brake.
Use left foot to control speed. Use ECO Mode to
limit speed.
6. Slowly drive straight up/down ramps (do not drive at
an angle).
7. Keep a firm grip on handlebars as the ramp is negotiated.
NOTE: Striper or grinder handlebars swing up/down as
the ramp is engaged/disengaged. Keep legs clear.

Operation
Charging the Batteries
Replace and charge battery only in well-ventilated
area and away from flammable or combustible materials, including paints and solvents. The charger may
become hot while charging. Do not touch. Refer to
Charger Manual for additional information.
The charger may be used any time the LineDriver is not
being used. When the batteries are fully charged, the
charger automatically stops. If the LineDriver is stored
for an extended period, the batteries may self-discharge
enough for the charger to automatically recharge the
batteries. For optimum battery life, always leave the
charger plugged in.
NOTICE
Lead acid batteries can self-discharge in as little as 3
months depending on storage temperatures. The hotter
the storage temperature, the faster the self-discharge
occurs. To prevent damage to the battery, it is important to keep the battery in a charged state.
Batteries are fully charged when leaving the factory.
Due to self-discharging of the battery, charge battery
before first use. It takes ~18 hours to charge a fully
depleted battery, and ~8 hours to charge the battery 3/4
full.
3. Ensure Power Switch is in OFF position.
4. Plug charging cord into charging port on the unit.
Connect an extension cord, per charger manual, to
the charging cord and plug it into wall power.
This equipment must be grounded to reduce the risk
of static sparking and electric shock. An electric
shock or static spark can cause fumes to ignite or
explode. An improper ground can cause electric
shock. A good ground provides an escape wire for
the electric current.
Always use an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided; if it does not fit the
outlet, have the proper outlet installed by a qualified
electrician.
NOTE: Battery life depends on the depth of discharge
per cycle. A battery that is discharged to 50% depth will
get over twice as many cycles in its life compared to it
being discharged to 100% depth each cycle.
1. Place unit in dry, well-ventilated area and away from
flammable or combustible materials, including
paints and solvents.
2. Position the driver so the wheels are on a true
grounded surface, not on pavement.
