RECOVERY TOWING
DANGER:
•
Before beginning recovery towing engine startup must be prevented (EVEN IF ENGINE
“WON’T START”). Turn off engine switch, remove key and zip tie pull start handle.
•
Engine, hydraulic components and hydraulic fluid get hot, allow adequate cooling time.
•
Avoid lifting heavy components.
Recovery towing:
Not considered normal operation,
If there is a malfunction that prevents the STK from providing its own mobility, such as an engine
failure, the STK may be towed a short distance (1/8 mile or 1/4 km). Select a path that minimizes
recovery towing distance and avoids hills.
•
Chock the tracks to prevent crawling (rolling).
•
Loosen both bypass valves, turn counterclockwise 2 turns. (DO NOT REMOVE)
•
Tie down attachment points can be used for recovery towing.
•
Remove chocks and tow as necessary.
NOTICE
:
•
DO NOT remove bypass valves: only turn counterclockwise 2 full turns.
•
DO NOT exceed 2mph (3kph).
•
When done towing,
tighten bypass valves to 100 in-lb. (11.3 Nm).
Manually raise boom: IF NECESSARY
•
Loosen hose on rear port of the boom cylinder. If necessary loosen hose on front port.
o
Oil will leak from port / hose, use rags to help minimize spilled oil.
•
Lift the boom with mechanical means such as a jack or fork lift.
•
If no mechanical means is available use at least 3 people, 2 strong workers to lift the boom
from the boom guard, 1 to tighten hoses.
