Operator`s manual

b) Air:
The hydraulic system and reservoir must be completely tight, except for a very small vent to take
care of any overflow due to expansion of the fluid.
Turbing oil indicates there is an improper amount of water or oil present. To determine if
cloudiness is present, place an oil sample in a test tube for at least one hour. If there is too
much water or air present in the oil, the following may occur:
Corrosion of hydraulic parts, or malfunction of hydraulic system (foam, air pockets, jerky
movement or sudden drop in pressure).
Gasoline, diesel fuel or any other chemical fluid may alter the oil in the hydraulic system. Metallic
particles, soot and dirt can cause mechanical damage to the hydraulic system components.
4.4.4 Lubricating
All grease fittings, joints of the ladder cylinders and joints of the base must be greased with a high
pressure gun from time to time.
NOTE: All sliding parts should be greased with "LUBRIPLATE LOW TEMP" or equivalent. This grease
can resist temperatures as low as -40 degrees. This operation is made simpler by extending
the ladder to its full length at 0 degrees. This will expose the slides, which can then be easily
cleaned and greased. It is very important that this maintenance work be done frequently -
possibly after each occasion the ladder is used at fire calls, since dirt or dust mixed with grease
forms a sticky, rubbery compound.
