Hi Kelly, Having looked at the opening discussion, it appears that Vic is not fully aware of the procedures and why its important to use the parking brake when using the Hydraulic controls. Mainly to prevent the truck from moving allowing the operative to concentrate on the task in hand, and to not assume that by having a foot on the service brake that everything will be fine. The reason that so many of the safe operating skills are forgotten can be due to the work pressures alot of operators find themselves under. Alot being attributed to inappropriate management practices.
