When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.
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.
