Do not leave out in direct heat.
When not in use, do not expose your handplane to direct sunlight or temperatures above 40°C. As such, protect your handplane by putting it in a bag, under a beach parasol, in the shade or under a light-coloured towel, so that it does not warm up. Never leave it in a car in direct sunlight. If the handplane is exposed to excessive heat, blisters or bubbles could form, or it could even warp.
