Clean the type with a brush and white spirit
place a cloth under the type bars and the brush them until clean
you might have to wipe each type bar clean to get rid of any excess liquid and dirt
a hard tooth brush is fine to clean the type
do not use a wire brush as that will damage the type face 

check that the type bars are entering the type guide correctly 

check that none of the plates are loose 

some times when the platen is hard it can sound tinny

also check the ring and cylinder
remove the ribbon
move the carriage so the platen is in the centre of the machine.
then feed a peace of paper round the platen
tare off a small peace of paper, then lift the “H” key lever
place the paper strip in front of the platen between the type face and the platen
hold the type bar on to the ring
then pull the paper up, there should be a slite resistance
if the paper will not pull out the platen is too near
if there is no resistance the platen is to far away
do this with the “W” and the “Q“ and at both ends of the platen 

if I think of anything else I will post it
 

1. I assumed that Royal manufactured its own slugs, but do you know for how many years the company produced its own slugs or where they were actually manufactured? 

I do not know the answer to this question, but all the machines I worked on built before 1953 in the US or Canada had Royal typefaces. After 1953 Royal started to build Typewriters in Holland and use Ransmayer type on these machines. 

2. Was it normal for slugs to be made in the same factory alongside the other parts of the machine? 

I am sorry but I do not know much about the manufacturing process but I do know that like other makers parts were bought in from small parts manufacturers . 

3. Why would Royal use German-made slugs for machines built in Holland, and its own slugs for those made in North America. 

It could have been cost or ease of manufacture. Ransmayer type had a serif on the top of the type face and if you used their type jig there was a slot that the serif doped into and guaranteed perfect alignment even when using inexperienced workforce. The workforce in Canada were more highly skilled then in Holland and that showed up in the final product. Royal were also trying to get into the German market and as Adler were using Ransmayer type, so having the same type styles put them into a better position to compete with them. 

4. Can you explain the term "motion"? 

This is the distance between the upper case and lower case characters on a type face and therefore the distance the segment moves (the motion) up and down. 

The reason for different lengths of motion was that the larger the diameter of the platen the longer the motion. Using short motion type on a large diameter platen would cause lower part of the upper case character appearing above the lower case character and vice versa. 

Ransmayer made type there own type styles in the following motions 6.6mm 7.6mm and 8.5mm. 

Some languages like Greek and Arabic were made in 7.73.mm, 7,25 and 8.0 mm

REMOVING AND REINSTALLING A ROYAL CARRAGE 
Remove the platen and feeds, this make the carriage lighter and easer to manage. 

Move the right hand margin stop to the right and the left margin stop to the left. 

Remove the carriage band and secure it on the right there should be a screw anchor if not anchor it some were it can not get loose. 

Now from the back of the machine move the carriage to the left (the line space lever in the centre) 

On the carriage you will see the carriage clamps first remove the clamps hanging over the of the base of the machine. Then loosen the screws of the centre one still on the rail NO NOT REMOVE. 

DO NOT REMOVE ANY OTHER CARRIAGE CLAMPS. 

Now move the carriage to the right of the machine and will be able to lift it off. 

Firstly move it towards you and lift so the carriage to release the carriage from the support rail then lift the end over the rail to release the back space lever it will now lift off. 

Now the carriage is off check the number of ball bearings and pinions there should be 2 for carriages of 16” or under and 4 for carriages over 16”. 

Clean the rails with oil and white mix spirit and check the escapement rack for damage and clean. 

Also check the escapement wheel and clean. 

TO REFIT THE CARRIAGE. 

Place the balls and pinions on the rail again with the back of the machine facing you. 

The one on the right 3 teeth from the end and the other one approximately 3 teeth from the centre. If there are 4 balls and pinions, position other two 6 teeth from the two you have just place on the rail to the centre on the rail. 

-----------------------------*----======----------------------------*----  

-----------------------------*----==*===--------------------*-------*---- 

Place the carriage back on the rail making sure the back support roller is sitting on the back rail and the backspace lever is above the escapement rack. 

Move the carriage slowly to the left and check the ball pinions are
