PUMP OPERATING INSTRUCTIONS:
1. To raise the chair, pump the foot bail DOWN with short stro es until the chair reaches
the desired height. Pushing the foot bail to the bottom of your foot stro e will decrease
the amount of lift per stro e.
2. To lower the chair, push down the foot bail all the way DOWN and hold.
3. To loc the chair rotation, lift UP on the bail after reaching the desired height.
IMPORTANT PUMP MAINTENANCE:
All hydraulic pumps must have air removed from the pump before use.
Pump the chair all the way up and down (three times) with a person in the chair.
This will circulate the hydraulic fluid throughout the pump, eliminating the air.
The client must enter and leave the chair in the “ALL THE WAY DOWN” position.
Always leave the chair in the lowest position every night.
These steps must be performed due to tipping and movement of the base during shipping
and everyday use.
