Page 8: Installation-Ski Attachment
Manual # GLH3000-105 Airglas, Inc. 3.0 Installation A modification to the landing gear must be accomplished at for installation of the Airglas, Inc. skis. If the aircraft landing gear has been previously modified for the LW2500 fixed Airglas, Inc. penetration skis, then no modification is necessary. 8.50 x 6 tires are required. Because there is a hydraulic pump that is required to actuate the skis, provision for this pump installation must be considered too. - Page 9 Switch sends power to the green or orange wire when “Wheels” are selected. This will pressurize the “DOWN” side of the pump. On (GLH3000) skis make sure the “UP” Port on the pump goes to the FWD fitting on the deployment Cylinder.

Page 10: Control And Operation
Page Revision B 4.0 Control and Operation Control and Operation Information: The door for the GLH3000 Ski is actuated by the electric/hydraulic pump (preferred) or a manually operated hand pump in the cockpit. The electric/hydraulic pump is controlled via a 3 position toggle switch and indicator lights that are located on the instrument panel. -
Page 11: Servicing Information
Hydraulic System – The hydraulic system supplied with the skis uses an Electric/Hydraulic Pump, (a hand pump is optional but not offered through Airglas, Inc.) to pump fluid to a hydraulic actuating cylinder mounted on the ski. The Electric/Hydraulic Pump is intended to be mounted behind the cabin area, preferably in the original aircraft battery location. -
