Reason:
To ensure that lift arms lower rear attachment completely and lower it at a safe rate of speed.
Equipment:
BW15073 Ballast Box
Procedure:
[1] – Park machine on a level surface and set park brake.
[2] – Shift transmission to NEUTRAL.
[3] – Install BW15073 ballast box, or approximately 227 kg (500 lb) , on the three point hitch.
[4] – Start engine and run at fast idle.
[5] – Put lift control lever in full UP position.
[6] – Raise weight as high as it will go.
[7] – Close rate of drop/stop valve.
[8] – Put lift control lever in full DOWN position.
[9] – Open rate of drop/stop valve 1-1/2โ2 turns.
[10] – Time duration of drop cycle from full up to full down.
Results:
If the weight lowers slower than specified time, open rockshaft rate of drop/stop valve until specification is met. If weight drop time will not meet specification, the rate of drop/stop valve may be clogged or faulty.
