Care of your guitar 
Here are some tips to help you keep your guitar in good playing condition:-

Do not expose it to extremes of temperature and/or humidity. If you must take it through temperature extremes, such as from a hot summer day into a chilled, airconditioned room, open the case slightly for a few minutes to let the guitar acclimatise gradually before removing it from the case.
Do not leave it in its case in direct sunlight or in a closed car. In the Australian climate this will generate temperatures within the case sufficient to soften adhesives and finishes and dramatically change the moisture content of the wood, causing permanent damage.
Do not expose your guitar to intense drying heat, such as a heater. This will cause rapid moisture loss from the wood which can, if extreme, cause shrinking and cracking of the soundboard.
Do not pick up your guitar by the body with one hand. Whilst the sides and back are quite thick and heavy, the edges of the soundboard are quite thin to improve volume and tone production. The pressure required from your thumb to counterbalance the weight of the body, neck and headstock may be sufficient to crack the soundboard.
Do not use wax, polish, abrasives, solvents or alcohol on the finish.
Do wipe the surface of the guitar after use with a soft dry cotton cloth. Cotton flannelette cloth is good for this purpose. Do not use synthetic cloths. They may scratch the finish.
Do wipe the strings and fretboard after use with a soft dry cloth. Whenever you change the strings give the fretboard a wipe and polish with a quality fretboard oil.
Do lubricate the gears of the tuning machines regularly, at least annually. Just a very small dab of sewing machine oil or Vaseline (petroleum jelly) where the crown gear meshes with the worm gear will keep the gears lubricated and prevent wear.
Do check the tightness of the screws which attach the buttons to the tuning machine shafts. Carefully tighten them if there is any free play between the button and the shaft.
Do be careful not to damage the soundboard behind the bridge when fitting and/or removing strings. A piece of cardboard placed on the soundboard immediately behind the tie-block will protect it from string ends.
Do keep the guitar in its case when not in use.
Do be careful of belt buckles, keys and coins in pockets, etc. They will mark the finish.
Do fit good quality strings, avoiding excessively high tension. Medium to high tension are fine. Choice of the tension and brand of strings is a matter of player preference and playing technique.
