Sheaves
Inspect the boom nose and hook block sheaves for proper
operation, excessive wear, and damage every 50 hours or
weekly. Inoperable, damaged and/or worn sheaves cause
rapid deterioration of rope.
Ensure sheaves carrying ropes that can be momentarily
unloaded are equipped with close fitting guards or other
devices to guide the rope back into the groove when the load
is reapplied. Ensure sheaves in the lower load block are
equipped with close fitting guards that will prevent the ropes
from becoming fouled when the block is lying on the ground
with loose ropes.
To attain maximum rope life and minimize hook block
rotation, it is recommended that even numbers of parts-of-
line be used in multiple-part reeving whenever possible.
The use of nylon (polyamide) sheaves, as compared with
metallic sheaves, may change the replacement criteria of
rotation-resistant wire rope.
NOTE: The use of cast nylon (polyamide) sheaves will
substantially increase the service life of rope.
However, conventional rope retirement criteria
based only upon visible wire breaks may prove
inadequate in predicting rope failure. The user of
cast nylon sheaves is therefore cautioned that a
retirement criteria should be established based
upon the user’s experience and the demands of his
application.
Batteries
Battery electrolyte must not be allowed to contact the skin or
eyes. If this occurs, flush the contacted area with water and
consult a doctor immediately.
When checking and maintaining batteries, exercise the
following procedures and precautions:
• Wear safety glasses when servicing batteries.
• If equipped, disconnect battery with the battery
disconnect switch before disconnecting the ground
battery cable.
• Do not break a live circuit at the battery terminal.
Disconnect the ground battery cable first when removing
a battery and connect it last when installing a battery.
• Do not short across the battery posts to check charge.
Short circuit, spark, or flame could cause battery
explosion.
• Maintain battery electrolyte at the proper level. Check
the electrolyte with a flashlight.
• If applicable to your equipment, check battery test
indicator on maintenance-free batteries.
• Check battery condition only with proper test equipment.
Batteries shall not be charged except in an open, well-
ventilated area that is free of flame, smoking, sparks,
and fire.
Engine
Fuel the equipment only with the engine turned off. Do not
smoke while fueling the equipment. Do not store flammable
materials on the equipment.
Be familiar with the location and use of the nearest fire
extinguisher.
Be careful when checking the engine coolant level. The fluid
may be hot and under pressure. Shut down the engine and
allow the radiator time to cool before removing the radiator
cap.
Shut down the engine and disconnect the battery before
performing maintenance. If unable to do so for the task
required, keep hands clear of the engine fan and other
moving parts while performing maintenance.
Be careful of hot surfaces and hot fluids when performing
maintenance on or around the engine.
Do not use ether to start the engine on equipment equipped
with intake manifold grid heaters.
TRANSPORTING EQUIPMENT
Before transporting the equipment, check the suitability of
the proposed route with regard to the equipment height,
width, length, and weight.
Check load limits of bridges on the travel route and ensure
they are greater than the combined weight of the equipment
and transporting vehicle.
When loading or unloading the equipment on a trailer or
railroad car, use a ramp capable of supporting the weight of
the equipment.
Ensure the equipment is adequately secured to the
transporting vehicle.
