Transmission Control Lever

Transmission control lever (

) engages forward or reverse travel.

• Lift and push lever forward for forward travel; lift and pull lever rearward for

reverse travel. Move lever to centered position for neutral.

• When traveling in reverse, the back-up alarm will automatically sound.

• Drive in reverse and turn only at slow rates of speed.

• Do not increase engine speed with the transmission in forward or reverse and the

service brake depressed in an attempt to get quicker hydraulic performances.
This could cause unexpected machine movement.

WARNING

TIP OVER/CRUSH HAZARD.

Bring telehandler to a complete stop before

shifting transmission control lever. A sudden change in direction of travel could
reduce stability and/or cause load to shift or fall.
