Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Hydrostatic motor and pump configuration includes one (1) or more of the following:

close coupled (motor and pump back to back units)

split units (separate motor and pump) single and double

multiple pump/motor layouts

series and parallel operation

fixed and variable displacement pumps

Control valves include one (1) or more of the following:

hot oil shuttle valves

cross-line relief valves

counterbalance valves

bypass valves

differential lock valves

parking brake valves

Hydrostatic special control features include one (1) or more of the following:

inch control

creep speed

brake defeat function

hydrostatic braking

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
