Lead from lead-based paints,
Crystalline silica from bricks and cement and other masonry products, and
Arsenic and chromium from chemically - treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out microscopic particles.
The purpose of safety symbols is to attract your attention to possible danger. The safety symbols and the
explanations with them deserve your careful attention and understanding. The symbol warnings do not, by

a) Check the scraper/auger and the mounting bolts at frequent intervals for proper tightness.
b) Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
c) Replace the auger if it is bent or cracked. An unbalanced auger causes vibration that could damage the
motor drive unit or cause personal injury.
d) Clean the auger thoroughly and check its balance by supporting it horizontally on a thin nail through its
center hole. The nail should also be in a horizontal position. If either end of the auger rotates downward,
remove some plastic from the heavy or lower end until the auger is balanced. It is balanced when neither
end drops.
1.Do not modify or attempt to repair the battery pack. Do not dismantle, open or shred battery pack.
2.Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or
temperature above 265°F (130°C) may cause explosion.
3.Do not short-circuit a battery pack. Do not store battery packs haphazardly in a box or drawer where they
may short-circuit each other or be short-circuited by other metal objects. 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.
4.Do not subject battery pack to mechanical shock.
5.Observe the plus (+) and minus (–) marks on the battery back and equipment and ensure correct use.
6.Keep battery pack out of the reach of children.
7.Always purchase the battery pack recommended by the device manufacturer for the equipment.
8.Keep battery pack clean and dry.
9.Wipe the battery pack terminals with a clean dry cloth if they become dirty.
10. Battery pack need to be charged before use. Always use the correct charger and refer to the
manufacturer’s instructions or equipment manual for proper charging instructions.
11.Do not leave battery pack on prolonged charge when not in use.
12. After extended periods of storage, it may be necessary to charge and discharge the battery pack several
times to obtain maximum performance.
13. Battery pack gives its best performance when it is operated at normal room temperature (20 °C ± 5 °C).
14.Use only the battery pack in the application for which it was intended. Do not use a battery pack or
appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.

19. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one typeof
battery pack may create a risk of fire when used with another battery pack.
20. Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
21. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally
