• Donotoperate c hain saw while
in a tree, on a ladder, on a scaffold, or from any unstable
surface.
• Hold tool by insulated gripping surfaces when performing an operation where the cutting
tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the
tool "live" and shock the operator.
• Do not attempt operations beyond your capacity or experience. Read thoroughly and
understand completely all instructions in this manual.
• Before you start chain saw, make sure saw chain is not contacting any object.
• Do not operate a chain saw with one hand! Serious injury to the operator, helpers, or
bystanders may result from one handed operation. A chain saw is intended for two-handed use
only.
• Keep the handles dry, clean, and free of oil or grease.
• Do not allow dirt, debris, or sawdust to build up on the motor or outside air vents.
• Stop the chain saw before setting it down.
• Do not cut vines and/or small under brush.
• Use extreme caution when cutting small size brush and saplings because slender material
may catch the saw chain and be whipped toward you or pull you off balance.
zLWARNING:
Use of this tool can generate and/or disburse dust, which may cause
serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away from face and body.
