Note: The float (detent) position for T-Bar controlled loaders is reached by
pushing the right handle all the way forward. For hand/foot controlled loaders,
use your toes to push the front of the left pedal all the way down.
Check that the work area is clear of people and
obstacles. Always look in the direction of
travel.
Vibration Information
Compact construction equipment is generally used in harsh environments. This
type of usage can expose an operator to uncomfortable levels of vibration. It is
useful to understand exposure to vibration levels when operating compact equip-
ment and what can be done to reduce vibration exposure. As a result, equipment
operation can be more efficient, productive and safe.
An operator’s exposure to vibration occurs in two ways:
Whole-Body Vibration (WBV)
Hand-Arm Vibration (HAV)
This section will cover primarily WBV issues, because evaluations have shown
that operation of mobile compact construction equipment on jobsites typically
results in HAV levels less than the allowed exposure limit of 2.5 m/s
2
.
Employers in Member States of the European Union must comply with the Phys-
ical Agents (vibration) Directive, 2002/44/EC.
Effective control of vibration exposure for an operator involves more than just
vibration levels on the machine. The job site, how the machine is used, and
proper training all play important roles in reducing vibration exposure.
Vibration exposure results from:
worksite conditions
how the machine is operated
the machine characteristics
Common causes of high WBV vibration levels:
Using a machine that is improper for the task
Work site with potholes, ruts and debris
Improper operating techniques, such as driving too fast
Incorrect adjustment of the seat and controls
Other physical activities while using the machine
