23 - Bleeding the cylinder
Considerations:
•
If the power unit (H1) will not run with the pendant (E38), refer to the BES3 service
manual section E
•
The hydraulic power units (H1) are adjusted and tested before shipping, although fine-
tuning may be required (best to wait until the end of the project). The pump will operate
without any adjustments.
Materials required:
•
None
Tools recommended:
•
½
inch wrench
•
A ladder may be required
Procedure:
•
Locate the bleed screw near the top of the cylinder and gain access
•
Turn the bleed screw halfway, the bolt is ground on one side so that it will let the air out.
•
Force the air out of the lines and cylinder
o
Press up on the remote pendant (E38) until the cylinder (H1) moves a few inches
o
Push down on the cylinder to force air out and then repeat above
Tip: stand to one side with a rag ready to go, as oil will come out when the air
stops
•
As the oil moves into the top of the cylinder, the pitch of the sound will increase
•
Sliding the high-speed switch o
ff
as the oil gets closer will limit the amount of oil that
comes out. It is located in the middle of the main controller board.
•
Continue forcing the air out of the cylinder (by running the power unit) until oil starts to
come out, then stop.
•
Tighten the bleed screw.
NOTE: This will remove the majority of the air, but after a few hours of sitting
an air pocket will reform at the top of the cylinder as the air mixed in with the
oil settles out. It is advisable after 30 minutes or more of not running the lift to
turn out the bleed screw half way and release that air. The air can also be bled
before running the elevator the morning of the second day.
