• Keep children and by standers away while operating the electric cart. Distractions can cause
you to lose control.
• When operating the machine, stand behind the machine and hold the handles firmly.
PERSONAL SAFETY
• This is not a toy. Children should not be allowed to operate it.
• Stay alert, watch what you are doing and use common sense when operating an electric cart. Do
not use an electric cart while you are tired or under the influence of drugs, alcohol or medication.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as
dust mask,non-skid safety shoes, hard hat, heav-duty working gloves, and hearing protection
used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power
source and/or BATTERY pack, picking up or carrying the tool.

OPERATION ON SLOPE WARNINGS
• Be sure to decrease speed and exercise caution on slopes.
• Exercise caution when starting or stopping the machine on slopes.
• As the loads become less stable on slopes, firmly secure the load.
• As the machine becomes unstable depending on the condition of the road, keep the load to a
minimum.
• As the view is obscured on slopes, keep the height of the load to a minimum
• Never park the machine on steep slopes. Park the machine on flat ground, pull the brake lever
and lock the brake, and then turn the power off.
• Do not change the direction or speed mode on steep slopes.
• Do not release the switch trigger on upward slopes. The machine may go in reverse and cause
an accident.
• Make sure that the remaining battery capacity is enough before operating on slopes. If the
remaining battery capacity is not enough, charge the battery or replace it with a charged one.
LOADING OBJECTIVE WARNINGS
• Do not overload objects. When loading objects, be sure to follow the instructions and load limits
in the manual.
• Firmly secure the objects.
• Load the objects within the carrier or bucket. If the objects protrude from the carrier or bucket,
there is a risk of accidents due to the objects falling or contact obstacles such as walls.
• Be sure that loaded objects are below eye level. If the load is too high, it is dangerous because
the view is obscured. Also, there is a risk of overturning and injury because the load is likely to
be unbalanced.
• Load the objects on the carrier or bucket evenly. If the objects are loaded unevenly, there is a
risk of overturning and injury because the load is likely to be unbalanced.
• Before loading the objects or operating the machine, make sure that the lock lever is fully pulled
down and completely locked.
• Load and unload objects on flat ground.
• When lifting and tilting the carrier or bucket, hold the handles and frame firmly, and work in a
stable posture.
BATTERY POWER TOOL USE AND CARE WARNINGS
• Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack
into the electric cart with the switch on may cause accidents.
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fire when used with another battery pack.
• Use the electric cart only with specifically designated battery packs. Use of any other battery
packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects like paper clips, coins,
keys, nails, screws, or other small metal objects that can make a connection from one terminal to
another. Shorting the battery terminals together may cause burns or fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. if contact acci-
dentally occurs, flush with plenty of soap and water. If liquid contacts eyes, immediately seek
medical help. Liquid ejected from the battery may cause irritation or burns.
