TION

WARNING:

WHEN THE BOOM IS

CONTROLLED MANUALLY FROM THE CONTROL
VALVE, THE ELECTRICAL LIMIT SWITCH WILL
NOT PREVENT OVER ROTATION.  DO NOT
ROTATE MORE THAN 180° FROM THE STORED
POSITION.

Operating Procedures At The Platform:

Complete  the  start-up  procedure  from  the  ground
before selecting the upper controls.  Verify that the
upper-boom  tie-down  strap  is  disengaged  when
entering the platform.  Safety regulations require the
operator be secured with a personnel restraint system
to the lift.  The lanyard shall be attached to the safety
belt/harness  and  the  other  end  connected  to  an
anchor located on the inner boom.  The safety belt
must  be  rotated  so  that  the  lanyard  connection  is
centered on the back of the operator.

DANGER:

NEVER OPERATE ANY

AERIAL EQUIPMENT WITHOUT WEARING AN
APPROVED PERSONNEL RESTRAINT SYSTEM
ATTACHED TO THE SPECIFIED ANCHOR.
FAILURE TO SECURE THE SAFETY BELT AND
LANYARD MAY RESULT IN DEATH OR SERIOUS
INJURY IN THE EVENT OF A FALL FROM THE
P

LATFORM.

PLATFORM LOCK - 

Versalifts with gravity leveling

are  equipped  with  a  positive  platform  locking  pin
which  prevents  movement  of  the  platform.  This
feature is not to be used while the lift is being 

raised

or lowered

, but is to be used as a way to eliminate

platform swing while the lift is stationary. The locking
mechanism  is  located  on  the  upper  telescoping
section of the boom, just above the platform pivot
point. The platform locking pin has two positions.
When the pin is fully engaged in the “platform locked”
position, the platform will not swing. When the pin is
pulled out and locked, the bucket will gravity level
itself.

To lock the platform in position

,  rotate  the  pin

counter-clockwise until the spring pulls the pin into
the boom. The pin should catch one of the locking
holes. If the platform still swings, it may be necessary
to rock the platform until the pin fully engages. In
this  position,  the  platform  will  not  level  when  the
boom is moved.

To deactivate the platform lock

, pull the pin out of

the boom and rotate it clockwise until the pin stays
disengaged.  If  the  pin  is  under  load,  it  may  be

necessary  to  rock  the  platform  in  the  opposite
direction to pull the pin freely. In this position, the
platform will be free to level when the boom is moved.

The platform lock should always be disengaged
while 

raising or lowering

 the lift.

To activate lift movement,

 the master control switch

must be activated in conjunction with the desired lift
function control switch.  See this section for further
details and a diagram of the upper control panel.

To terminate any lift movement,

 allow the control

switch to return to the centered or neutral position.

The upper controls have been designed to provide
convenient and comfortable access for the operator.
These  controls  are  also  carefully  protected  from
damage.  Two  or  three  controls  may  be  operated
simultaneously, depending on the platform load and
which functions are being operated.  If the platform
is heavily loaded and the two controls being operated
require high pressure (e.g. “extend” and “raise”) the
total system pressure may exceed the setting of the
relief valve.  This causes oil to bypass the relief valve.
This is not detrimental to the aerial lift but results in
noise and reduced operating speeds and should not
be  done.  Practice  and  experience  will  prove
invaluable in becoming proficient with the aerial lift
controls.

Operating Where Electrical Hazards Are Present:

It is imperative that the operator of the aerial device
understand the dangers associated with operating
near electrical hazards.  Due to the work involved,
the  ordinary  uses  of  aerial  lifts  often  place  the
operator, others in the platform, and ground crew in
the vicinity of electrical lines and equipment where
grave danger exists.  These dangers can only be
avoided by the constant care of an operator who is
aware of these dangers, knows the limitations of the
aerial lift, and knows how to protect himself and the
crew from these dangers.  Maintain safe clearances
from  electrical  power  lines  in  accordance  with
applicable government regulations.  Allow clearance
for boom, platform, electrical line, and load line sway
and deflection.

DANGER:

ALL COMPONENTS IN

THE PLATFORM AREA, INCLUDING THE
CONTROLS, JIB POLE, COVERS, ETC. SHALL
BE CONSIDERED ELECTRICALLY CONNECTED,
AND NOT INSULATED OR ISOLATED.  THESE
COMPONENTS MAY CONDUCT ELECTRICITY
RESULTING IN DEATH OR SERIOUS INJURY.
