45°
SAFE DEPTH OF CUT WILL DEPEND ON 4 FACTORS:

- MISSING/DAMAGED TIPS ON 6 OR MORE CUTTERS AT RANDOM
- CRACKED/BROKEN TIE STRAPS
- DULL CHAIN
WHAT ARE THE DAILY CHECKS OF A CHAINSAW?
- CHECK FUEL LEVEL
- CHECK LUBRICATING OIL LEVEL
- CHECK CHAIN CONDITION, TENSION, AND PROPER DIRECTION OF TRAVEL
- CHECK CONTROLS FOR PROPER STARTING POSITION
- CHECK CARRYING STRAP AND HOOKS FOR CONDITION
- CHECK GAUNTLET GLOVES FOR PROPER LOCATION AND CONDITION
- MAKE A VISUAL CHECK OF ENTORE CHAINSAW FOR LOOSE FASTENERS AND/OR COVERS
WHAT ARE THE WEEKLY CHECKS OF THE CHAINSAW?

WHAT ARE THE MONTHLY CHECKS OF THE CHAINSAW?
- PERFORM DAILY CHECKS
- REMOVE SPARK PLUG. CHECK GAP AND CONDITION. CLEAN, REGAP OR REPLACE IF NECESSARY.

- INSPECT SECURITY OF CARBURETOR AND ALL LINKAGE
CHAIN TENSION IS CORRECT WHEN IT FITS SNUGLY AGAINST THE UNDERSIDE OF THE BAR BUT CAN STILL BE PULLED EASILY ALONG THE BAR BY HAND
TRUE/FALSE
TRUE
WHAT ARE THE 3 IMPORTANT FUNCTIONS THAT MUST BE PERFORMED PRIOR TO DISASSEMBLING THE CHAIN SAW?
