Operation And Maintenance; Maintenance And Storage - GRAPHITE PRO 59GP300 Manual De Instrucciones

Do not apply excessive pressure on the wall chaser, do not push it forward forcefully. Pressure
while plunging and moving should be moderate. Applying excessive pressure may cause motor
overheating and damage of the cutting blade.
Cutting blades heat up to high temperatures during operation – do not touch them with unprotected
parts of your body before they cool down.
When cutting very hard materials, cutting blade may be overheated and damaged in consequence.
Shower of sparks around the cutting blade indicates overheating. When it appears, immediately
stop cutting and cool down the blade by running it with full rotational speed with no load for 3–5
minutes.
Noticeable decrease of cutting efficiency and shower of sparks around the cutting blade may
indicate blunt cutting blade.
Use only working tools whose allowable rotary speed is higher or equal to maximum wall chaser
speed with no load.
Unplug the power cord from mains socket before commencing any activities related to installation,
adjustment, repair or maintenance.
