SAFETY WARNINGS

General power tool safety warnings

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Battery-powered wheelbarrow safety warnings

While operating the machine, always wear nonslip and protective footwear. Non-skid, closed-toed safety boots and shoes will reduce the risk of injury.
Inspect pathway before hauling objects/materials. Familiarizing yourself with the pathway and ensuring it is wide enough to safely navigate the machine under load will help reduce losing control of the machine.
Use extreme caution on slippery, loose and unstable terrain. Wet and slippery surfaces, such as wet grassy areas, snow or ice, and loose and unstable terrain, such as sand or gravel surfaces, may cause the machine to lose traction and may adversely affect steering, braking and stability.
Do not operate the machine on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury. Slopes greater than the maximum recommended grade and side grades may increase the risk of instability and may adversely affect the ability to stop safely.
When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down, and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
Whenever possible, use level areas for stopping, loading and unloading and never leave machine unattended on a slope. The machine is more unstable when resting on a slope than when resting on a level surface.
When leaving the machine unattended, set parking brake once the machine is located in a safe stopping area. The parking brake prevents unwanted movement of the front wheel and can improve stability.
Ensure that ramps are clean, strong and secure. In order to reduce the risk of injury, all ramps must be clear of loose debris and strong enough to withstand the weight of anticipated loads that will be moved over them. They must have adequate blocking underneath and to both sides to eliminate deflections and side-to-side movement under load. All ramps must be wide enough to have sure footing while hauling loads across them.
Ensure all locking screws are tightly secure before using. Locking screws on the rear wheels and open-type carrier front and side walls must be secure to prevent unwanted movement of these adjustable parts of the machine.
Never operate the machine in an overloaded condition. Make sure the machine has the proper capacity rating for the objects or materials that have to be hauled. Excessive loads will make the machine more difficult to maneuver and stop, will increase stopping time and distance, and will increase the risk of instability.
Never operate your machine in an over-stacked condition. Stacking material above the tray rim or over the sides of the tray can cause the machine to be uncontrollably out of balance and control.
Use containers and tie-downs to secure loads. Loose and/or insecure loads are more likely to shift which can result in loss of stability and control.
Always maintain a firm grip on handles. Loss of control can increase the risk of personal injury.
Remove safety key when not in use. The safety key prevents unwanted, powered use of the machine, such as by children or other untrained or unauthorized persons. Without the key, electric power cannot be turned “on”.
This machine cannot be used on public roads. Use of the wheelbarrow on a public road is unlaw-ful and could result in local jurisdiction penalties in addition it could result in personal injury.
Use a sturdy plate with anti-slip and detach-ment prevention function when loading and/or unloading this machine for transportation, or moving this machine between different levels. Make sure the plate inclination does not exceed 12°, and operate the machine slowly and carefully. Unstable and quick operation may result in overturn and/or falling.
Do not disassemble, repair, or modify this machine.

Preparation

Before operating the machine, make sure that there are no people around the machine.
Before operating the machine, perform the inspections referring to the section for maintenance.

Operation

When operating the machine, stand behind the machine and hold the handles with both hands firmly.
Do not operate the machine while riding on the machine.
Do not allow others to ride on the machine.
When operating the machine in reverse and walking backward, watch behind you and watch your step, and be careful not to slip or trip.
Do not use the machine when visibility is poor because there is a risk of striking obstacles.
When operating the machine on rough ground or going over the level difference of the road, decrease speed and exercise caution.
When using the machine, avoid soft ground to prevent overturn due to the shoulder of the road collapsing.
Do not operate the machine on upward slopes greater than 12°.
If you find an abnormality, stop the machine on flat ground. Before inspecting the machine, lock the brake lever, and then turn the power off.
Before operating the machine, make sure that the handle of the dump unit is fully pulled down and completely locked. If the lock is incomplete, there is a risk of accident or injury as the carrier or bucket may be tilted and the objects fall when going downhill.
When operating the machine near walls, be careful not to get your hands caught between the handle and the wall.
Do not use the machine in bad weather condi-tions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
Do not touch the metal parts during use or after use as they may get hot enough to cause burns due to sunlight.
Be careful not to entangle the cords with the load or obstacles.
When crossing a wooden bridge, etc., make sure that the sum of the weight of product, load capacity, and operator’s weight does not exceed the weight limit of the bridge, and cross the bridge carefully at a constant speed.
Wear the gloves when operating the machine in low temperature environments. Touching the metal parts with bare hands may cause your hands to stick.
If there are people or obstacles in the direction of travel, avoid them in advance.
Do not scoop objects directly with the carrier or bucket. Doing so may damage the machine and cause an accident.
When you use the machine on muddy ground, wet slope, or slippery place, pay attention to your footing.
Do not submerge the machine into a puddle.

Operation on slopes

Do not cross on slopes.
Stop before the downhill, and be sure to decrease speed and exercise caution.
If the speed is too fast when traveling downhill, the beep sound is emitted. In this case, slow down using the brake.
Exercise caution when starting or stopping the machine on slopes.
As the loads become less stable on slopes, firmly secure the loads with ropes.
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 stop the machine on slopes. Stop the machine on flat ground, and lock the brake lever, 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.
When starting the machine on slopes, do not place your foot behind the rear wheel since the machine moves back a few centimeters.

Loading objects

Do not overload objects. When loading objects, be sure to follow the instructions and load limits in the manual.
Since the larger the load, the more difficult it is to operate the machine, keep the load within the range that does not affect the operation.
Firmly secure the objects with ropes.
Load the objects within the carrier, bucket, or flat bucket. If the objects protrude from the carrier, bucket, or flat 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, bucket, or flat 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 handle of the dump unit is fully pulled down and completely locked.
Be sure to load heavy objects first to keep balance.
Do not extend the front and side rails on steep slopes. Extend the side rails when lightweight objects are loaded.
When extending the front and side rails, do not extend them over the extension limit. Be sure to extend the side rails so that the right and left sides are the same length, and load objects evenly.
Load and unload objects on flat ground. Never load or unload objects on slope.
When lifting and tilting the carrier or bucket, hold the handles and frame firmly, and work in a stable posture.
When loading liquids, be careful not to spill them. Spilling them may cause slipping and cause an injury.

Transportation of machine

Use the ladder rails that are at least 4 times as long as the height of the truck bed, with fixtures suitable for the bed, with a non-slip surface and sufficient width, and capable of withstanding the weight of the machine and operator. Read the instruction manual of the ladder rails carefully before use.
Before loading the machine, unload all objects from the machine and remove mud and other debris from the tires. Install the ladder rails on a flat and stable surface.
Before loading or unloading the machine, make sure that there are no people around the machine and the ladder rails. Load or unload the machine at low speed, taking care to prevent the machine from falling off the ladder rails, and not to hit your head on the ceiling of the truck. Use extreme caution when loading or unloading the machine backward.
When transporting the machine, lock the brake lever, turn the power off, remove the batteries and lock key, and fix the machine securely.
