(A) 12 degrees
Complete the following steps in order to measure the swing speed on a slope.
Start the engine.
Place the engine speed dial in the HIGH IDLE position.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Load the bucket .Weight of bucket load ... 105 kg (231.5 lb)
Position the machine on a slope of 12 degrees. Refer to Illustration 1.
Position the implements at maximum reach and close the bucket. Position the bucket above the ground so that the bucket will not come in contact with any obstacles.
Place the engine speed dial in the LOW IDLE position.
Illustration 2 g01154250
Position the upper structure at position (X) . The upper structure should be at a 90 degree angle to the lower structure. Refer to Illustration 2.
Measure the time that is required to swing the upper structure from position (X) to position (Y) .
Position the upper structure at position (Z) . The upper structure should be at a 90 degree angle to the lower structure.
Measure the time that is required to swing the upper structure from position (Z) to position (Y) .

(A) Upper frame (B) Undercarriage frame (C) Marking
To indicate the relationship of the two positions, put a mark (C) on the inner race and the outer race of the swing bearing. Refer to Illustration 4.
Start the engine. Position the implements at maximum reach. Place the engine at the LOW IDLE position. Place the hydraulic activation lever in the UNLOCKED position.
Leave the machine in this position for three minutes. Measure the swing drift on the circumference of the swing bearing.
Position the upper structure at position (Z) . The upper structure should be at a 90 degree angle to the lower structure. Refer to Illustration 3.
Repeat Steps 2.c through 2.e.
