2) Inspect oil level

Figure 1-1 Traveling slowdown

1. Oil filler 2. Viewing port

Drive the machine until one plug is located

at the horizontal position as shown as

shown in Figure 1-1.

Remove the viewing port plug at the

horizontal position, and inspect oil level.

Result: Oil level shall be flush with the

bottom of the viewing port.

If necessary, add oil at the oil filler until the

oil level is flush with the bottom of the

viewing port, select gear oil by referring to

Machine Specifications section.

Coat the plugs with pipe thread sealant and

install the plugs.

Maintenance Manual of Elevating Work Platform

Figure 1-2 Oil Level Sight Gauge

Examine the oil level on the hydraulic oil

tank, i.e., level shall fall within the M range

shown as Figure 1-2, and in the case of

level lower than L, it is necessary to add

hydraulic oil.

2) Inspect hydraulic oil leakage every 8 h or
