Makita 5014B, Instruction Manual

When the log is supported along its entire length as 
shown in 

Fig. 16

, it is cut from the top (overbuck).

When the log is supported on one end, as shown in 

Fig. 17

, cut 1/3 the diameter from the underside 

(underbuck). Then make the finished cut by overbucking 
to meet the first cut. 
When the log is supported on both ends, as shown in 

Fig. 18

, cut 1/3 of that diameter from the top overbuck. 

Then make the finished cut by underbucking the lower 2/3 
to meet the first cut. 
When bucking on a slope, always stand on the uphill side 
of the log, as shown in 

Fig. 19

. When “cutting through”, to 

maintain complete control, release the cutting pressure 
near the end of the cut without relaxing your grip on the 
chain saw handles. Don’t let the chain contact the ground. 
After completing the cut, wait for the saw chain to stop 
before you move the chain saw. Always stop the motor 
before moving from tree to tree. 

Carrying tool 

Carry the tool by the front handle with the tool turned off, 
finger off the switch, the guide bar and the saw chain to 
the rear. Use the scabbard to cover the guide bar and the 
saw chain.

MAINTENANCE 

 CAUTION:

Always be sure that the tool is switched off and unplugged 
before attempting to perform inspection or maintenance. 

Filling saw chain 

To get the most in cutting performance from your tool, you 
must keep the cutters sharp and filed properly. 

(Fig. 21)

To file the saw chain, push the file in the direction of the 
arrow. When pulling it back, be careful not to touch the 
cutters with the file. 

(Fig. 22)

After a saw chain has been filed two or three times, the 
“raker” (see 

Fig. 21

) may need to be filed down slightly. 

This is because the raker acts as a depth gauge for the 
cutters. As the cutters are filed, they lose some height due 
to their angled shape. Eventually, the cutters will become 
lower than the depth gauge and consequently, will not be 
able to cut. To remedy this, use a flat file to file the tops of 
the rakers so that they are about 0.5 mm below the tips of 
the cutters (see 

Fig. 21

). Be careful not to file the rakers 

excessively or the cutters will be allowed to take too large 
of a “bite”, causing the tool to stall or snag in the cut. 

Removing chip buildup 

Chips and sawdust will build up in the guide bar groove 
and oil hole, clogging them and impairing oil flow. Remove 
the guide bar and clean them out. 

(Fig. 23 & 24)

Replacing carbon brushes 

Remove and check the carbon brushes regularly. Replace 
when they wear down to the limit mark. Keep the carbon 
brushes clean and free to slip in the holders. Both carbon 
brushes should be replaced at the same time. Use only 
Makita carbon brushes. 

(Fig. 25)

Use a screwdriver to remove the brush holder caps. Take 
out the worn carbon brushes, insert the new ones and 
secure the brush holder caps. 

(Fig. 26)

Storing the tool 

Before storing the tool, be sure to do the following: 
• Remove the chain cover. Remove any chips and 

sawdust from the tool. 

• Install the chain cover. Turn the tool on and depress 

the oil button 4 or 5 times. 

• Cover the saw chain and the guide bar with the 

scabbard. 

To maintain product SAFETY and RELIABILITY, repairs, 
any other maintenance or adjustment should be 
performed by Makita Authorized or Factory Service 
Centers, always using Makita replacement parts.
