Hino e2004 clutch adjustment? and front end leak

[agcomike]

1) I was wondering on left side where the clutch pedal is what does that yellow decal state? (looks like something about adjusting or something?)

2) Need info on clutch/clutch pedal adjustment

3)i noticed my pto shaft moving everyonce in a while (1/4-1/2 turn at a time maybe normal?) when the pto lever was off maybe related to needing clutch adjustment?

4)also have a transmission leak at the front axe u-joint area where the driveshaft comes into the front axle it's spilling trans fluid when i park on slight incline is the seal on back of trans or in front? also do you have to remove front axle to get shield/driveline off?

thanks
