the Maintenance section of this manual.
USE PROPER EXTENSION CORD:
Make sure your extension cord is in good condition.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

4. Be sure the bit is secured in place before
operation.
5. Under normal operation, the tool is
designed to produce vibration. The
screws can come loose easily, causing a
breakdown or accident. Check tightness
of screws carefully before operation.
6. In cold weather or when the tool has not
been used for a long time, let the tool
warm up for a while by operating it under
no load. This will loosen up the lubrication. Without proper warm-up, hammering
operation is difficult.
7. Always be sure you have a firm footing.

tool in high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the
tool only when hand-held.
11. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
12. Do not touch the bit or parts close to the
bit immediately after operation; they may
be extremely hot and could burn your
skin.
13. Some material contains chemicals which
may be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material supplier safety data.
