adjustable throttle valve (flow control) shall be located as close as practicable to the lift
cylinder(s) to limit and control the downspeed. The throttle valve shall be rated for not less than
three times the working pressure and shall be equipped with a lock screw or jam nut to hold the
desired preset. When two lift cylinders are provided, a manifold shall distribute equal pressure
and flow rate and shall provide for simultaneous operation of the cylinders. Controls. Hoist controls shall be electrically operated and shall be of the dead man
type. Means shall be provided for manual operation of the controls in the event of an electrical
failure. The controls shall be metered to provide gradual starting and stopping of the hoist and to

Additional interlocks shall be provided to prevent the transmission from engaging a forward or
reverse gear when the outriggers are down. Outrigger controls shall be installed in a readily
accessible location allowing operation from the driver's seat. Outrigger cylinders, hydraulic
fittings, hoses and pilot check valves shall be protected by metal guards and shall be accessible
for service. An automatic pilot check valve shall be provided for each outrigger to block the
hydraulic fluid in the cylinder and to prevent movement of the outriggers in the event of a
damaged hydraulic line. Each outrigger shall be provided with an automatic, positive,
spring-actuated lock, or an automatic pilot check valve which will hold the outrigger in the
retracted position without settling and which may be manually released. Each outrigger shall be
provided with a ground pad. Ground pads shall be of the hinged or fixed type, each not less than
