GENERAL PRECAUTIONS - CONTINUED
LOWER OR SUPPORT RAISED EQUIPMENT
Do not work under raised booms without supporting them. Do not use support material
made of concrete blocks, logs, buckets, barrels, or any other material that could
suddenly collapse or shift positions. Make sure support material is solid, not decayed,
warped, twisted, or tapered. Lower booms to ground level or on blocks. Lower booms
and attachments to the ground before leaving the cab or operator’s station. Whenever the boom
structure must be raised for attachment installation or servicing block ensure the boom locking
devices (if equipped) are deployed to prevent the accidental lowering of boom structures.
NEVER PLACE ANY BODY PART BETWEEN THE PRIME MOVER CHASSIS AND THE BOOM
STRUCTURE! Refer to the operating and maintenance instructions provided by the prime mover
manufacturer for specifi c information.
USE CARE WITH SILICA DUST DURING OPERATION
Concrete and masonry products contain silica sand. Quartz, which is a form of silica and the most
common mineral in the earths crust, is associated with many types of rock. Some activities that
silica dust may be present in the air include demolition, sweeping, loading, sawing, hammering,
drilling, or planing of rock, concrete or masonry.
It is recommended to use dust suppression, dust collection or personal protective equipment
during the operation of any attachment that may cause high levels of silica dust.
The NIOSH recommended exposure limit for respirable crystalline silica is 0.05 mg/m3 as a time-
weighted average for up to 10 hours/day during a 40-hour workweek [NIOSH 1974].
USE CARE WITH HYDRAULIC FLUID PRESSURE
Hydraulic fl uid under pressure can penetrate the skin and cause serious injury or
death. Hydraulic leaks under pressure may not be visible. Before connecting or
disconnecting hydraulic hoses, read your prime mover’s operator’s manual for
detailed instructions on connecting and disconnecting hydraulic hoses or fi ttings.
• Keep unprotected body parts, such as face, eyes, and arms as far away as
possible from a suspected leak. Flesh injected with hydraulic fl uid may develop
gangrene or other permanent disabilities.
• If injured by injected fl uid, see a doctor at once. If your doctor is not familiar with
this type of injury, ask him to research it immediately to determine proper treatment.
• Wear safety glasses, protective clothing, and use a piece of cardboard or wood
when searching for hydraulic leaks. DO NOT USE YOUR HANDS! SEE ILLUSTRATION.
