2.4 FUNCTION CHECK
The function check of all systems should be performed in an area
free of overhead and ground level obstructions. Perform a function
check as follows:
1. Set-up machine for operation, according to operating
instructions in Section 4.
2. Enter platform, raise and lower platform 2 ft. to 3 ft.
(.61m to .92 m) several times. Check for smooth eleva-
tion and lowering of platform.
3. With the aid of an assistant in the platform, test the man-
ual decent valve. Elevate the platform approximately 12
inches, then activate the manual decent function, pull
and hold the red knob until the platform is completely
lowered.
4. Ensure that all machine functions are disabled when the
Emergency Stop Switch is pressed.
5. With platform completely lowered, check hydraulic oil
level in reservoir at ground control station. Maintain an
oil level to the "Fill to Line" indicator on the side of the
reservoir. NEVER USE HYDRAULIC BRAKE FLUID.
6. If equipped with the optional platform gate interlocks,
verify the lift function does not operate with either gate
open.
NOTE: To verify if the machine is equipped with the optional gate
interlocks, look for a wire harness to exit the platform mid-
rail through a small hole in the midrail near the mast
header.
7. Machines equipped with the optional platform foot
switch controls, check proper operation for elevating
and lowering of the platform.
