7.3 Pre-start Checklist
Items to Complete
Check the machine for entangled material. Remove
any twine, wire, or other material that has become
entangled.
Check that all the fasteners are installed and
tightened to the correct torque.
Make sure that your equipment is working properly
and in good repair.
Check the hydraulic system for leaks. Use a safe
method to inspect for leaks. Tighten fittings or
replace components, as required.
Check the hydraulic fluid level. Add hydraulic fluid,
as required.
7.4 Loading
•
All coworkers must be in view before logs or equipment are
moved.
•
Have the logs ready to be loaded so work can be done in a
safe manner. Turn logs that must be loaded but end first to
eliminate extra maneuvering when loading.
•
Load logs to ensure the stability of the vehicle and load
while in transit.
•
Load and unload from the side of the truck or trailer. Make
sure there is enough clearance for the excavator to swing
between the trailer/truck and other obstacles.
•
Do not overload trucks or trailers. Keep the loads uniform
by alternating butt ends of logs. Conform to regulations for
height, weight, and length of loads.
•
Position logs to avoid excessive strain on trailer stakes. Lay
logs onto the trailer tightly, in a consistent manner without
crowding.
•
Never place split, cracked, or shattered logs on the bottom
of the bunk or up against the bunk stakes.
•
Operate carefully when the grapple is loaded. Elevated
loads reduce machine stability on unstable ground.
•
Balance loads in the grapple so the weight is evenly
distributed and stable.
•
Reduce speed before turning or swinging a load.
•
Logs must extend past bunk stakes 12 inches (30 cm).
•
Place two tiers of logs onto the bunk before loading shorter,
smaller diameter logs.
•
Take care to balance the load on the trailer or truck. An
unbalanced load could cause a tip over.
•
Balance loads carefully. Determine where the center of the
load is in order to pick it up safely. The stump end of logs
can be heavier and the smaller ends lighter.

Make sure the grapple contacts all of the load
•
Make sure grapple forks have full contact with all the pieces
you are lifting. Otherwise the load could become unstable
causing a dangerous situation to coworkers.

Fig. 19 –
Grapple forks must be around the load when they are closed
•
Pick loads up so that the weight is balanced in the grapple.
This point may not be at the exact center of the load. The
stump-end of a log for example, may cause it to be heavier
at that end so you have to pick it up closer to that end.
