HL 91 level indicators are directly connected to the reservoir to check the level and temperature of the hydraulic fluid.
There are 3 different dimensions available with difference between centers of 3 in (76 mm), 5 in (127 mm) and 10 in
(254 mm) and are equipped with M10 or M12 fixing screws.
Versions with a thermometer are also available.
The external protection is made of anodized aluminum to provide strong impact resistance, while the central body is
made of see-thru polyamide.

ASSEMBLY INSTRUCTIONS
The connection of the HL 91 level indicators is done through the built-in-screws. After they pass the tank's drilled wall
they have to be mounted using the supplied nuts to a torque of 88.5 lbf in (10 Nm).
Before connecting make sure there are no burrs in the screws mounting seats.

NOTE
To avoid accidental impacts that
might break the level indicator and
cause oil leaks, we suggest to
arrange additional protection of the
tank.
