Makita MAC5200 Owner's Manual page 40

Keep the air hose away from heat (over 6OoC, over 140°F),
away from chemicals (thinner, strong acids or alkalis). Also,
route the hose away from obstacles which it may become
dangerously caught on during operation. Hoses must also
be directed away from sharp edges and areas which may
lead to damage or abrasion to the hose.
To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita
Authorized or Factory Service Centers, always using Makita replacement parts.
